This commit adds a pyscript variant for use in https://pyscript.net/.
The configuration is:
- No ASYNCIFY, in order to keep the WASM size down and have good
performance.
- MICROPY_CONFIG_ROM_LEVEL_FULL_FEATURES to enable most features.
- Custom manifest that includes many of the python-stdlib libraries.
- MICROPY_GC_SPLIT_HEAP_AUTO to increase GC heap size instead of doing a
collection when memory is exhausted. This is needed because ASYNCIFY is
disabled. Instead the GC collection is run at the top-level before
executing any Python code.
- No MICROPY_VARIANT_ENABLE_JS_HOOK because there is no asynchronous
keyboard input to interrupt a running script.

With this commit, `interpreter.runPythonAsync(code)` can now be used to run
Python code that uses `await` at the top level. That will yield up to
JavaScript and produce a thenable, which the JavaScript runtime can then
resume. Also implemented is the ability for Python code to await on
JavaScript promises/thenables. For example, outer JavaScript code can
await on `runPythonAsync(code)` which then runs Python code that does
`await js.fetch(url)`. The entire chain of calls will be suspended until
the fetch completes.

This commit improves the webassembly port by adding:
- Proxying of Python objects to JavaScript with a PyProxy type that lives
on the JavaScript side. PyProxy implements JavaScript Proxy traps such
as has, get, set and ownKeys, to make Python objects have functionality
on the JavaScript side.
- Proxying of JavaScript objects to Python with a JsProxy type that lives
on the Python side. JsProxy passes through calls, attributes,
subscription and iteration from Python to JavaScript.
- A top-level API on the JavaScript side to construct a MicroPython
interpreter instance via `loadMicroPython()`. That function returns an
object that can be used to execute Python code, access the Python globals
dict, access the Emscripten filesystem, and other things. This API is
based on the API provided by Pyodide (https://pyodide.org/). As part of
this, the top-level file is changed from `micropython.js` to
`micropython.mjs`.
- A Python `js` module which can be used to access all JavaScript-side
symbols, for example the DOM when run within a browser.
- A Python `jsffi` module with various helper functions like
`create_proxy()` and `to_js()`.
- A dedenting lexer which automatically dedents Python source code if every
non-empty line in that source starts with a common whitespace prefix.
This is very helpful when Python source code is indented within a string
within HTML or JavaScript for formatting reasons.

This commit cleans up and generalises the Makefile, adds support for
variants (following the unix port) and adds the "standard" variant as the

Enabled by MICROPY_COMPILE_ALLOW_TOP_LEVEL_AWAIT. When enabled, this means
that scope such as module-level functions and REPL statements can yield.

This workaround makes sure that all ringbuf functions that may be called
from an ISR are placed in IRAM. See
https://github.com/espressif/esp-idf/issues/13378
Note that this means that all esp32-og builds get non-ISR ringbuf functions
placed in flash now, whereas previously it was just the spiram variant.
This might be a good thing (e.g. free up some IRAM for native/viper).
Fixes issue #14005.

This fixes a bug where a random Python object may become
un-garbage-collectable until an enclosing Python file (compiled on device)
finishes executing.
Details:
The mp_parse_tree_t structure is stored on the stack in top-level functions
such as parse_compile_execute() in pyexec.c (and others).
Although it quickly falls out of scope in these functions, it is usually
still in the current stack frame when the compiled code executes. (Compiler
dependent, but usually it's one stack push per function.)
This means if any Python object happens to allocate at the same address as
the (freed) root parse tree chunk, it's un-garbage-collectable as there's a
(dangling) pointer up the stack referencing this same address.

This commit implements a new <AbstractNIC>.ipconfig() function for the NIC
classes that use lwIP, to set and retrieve network configuration for a NIC.
Currently this method supports:
- ipconfig("addr4"): obtain a tuple (addr, netmask) of the currently
configured ipv4 address
- ipconfig("addr6"): obtain a list of tuples (addr, state,
prefered_lifetime, valid_lifetime) of all currently active ipv6
addresses; this includes static, slaac and link-local addresses
- ipconfig("has_dhcp4"): whether ipv4 dhcp has supplied an address
- ipconfig("has_autoconf6"): if there is a valid, non-static ipv6 address
- ipconfig(addr4="1.2.3.4/24"): to set the ipv4 address and netmask
- ipconfig(addr6="2a01::2"): to set a static ipv6 address; note that this
does not configure an interface route, as this does not seem supported by
lwIP
- ipconfig(autoconf6=True): to enable ipv6 network configuration with slaac
- ipconfig(gw4="1.2.3.1"): to set the ipv4 gateway
- ipconfig(dhcp4=True): enable ipv4 dhcp; this sets ipv4 address, netmask,
gateway and a dns server
- ipconfig(dhcp4=False): stops dhcp, releases the ip, and clears the
configured ipv4 address.
- ipconfig(dhcp6=True): enable stateless dhcpv6 to obtain a dns server
There is also a new global configuration function network.ipconfig() that
supports the following:
- network.ipconfig(dns="2a01::2"): set the primary dns server (can be a
ipv4 or ipv6 address)
- network.ipconfig(prefer=6): to prefer ipv6 addresses to be returned as
dns responses (falling back to ipv4 if the host does not have an ipv6
address); note that this does not flush the dns cache, so if a host is
already in the dns cache with its v4 address, subsequent lookups will
return that address even if prefer=6 is set
This interface replaces NIC.ifconfig() completely, and ifconfig() should be
marked as deprecated and removed in a future version.

The C-based SPI flash driver is needed because the
`_copy_file_to_raw_filesystem()` function must copy from a filesystem (eg
FAT) to another part of flash, and the same C code must be used for both
reading (from FAT) and writing (to flash).

The argument to MP_BC_MAKE_FUNCTION (raw code index) was being encoded as a
byte instead of a variable unsigned int. That meant that if there were
more than 128 merged mpy files the encoding would be invalid.
Fix that by using `mp_encode_uint(idx)` to encode the raw code index. And
also use `Opcode` constants for the opcode values to make it easier to
understand the code.

Add `pop()`, `appendleft()`, and `extend()` methods, support iteration
and indexing, and initializing from an existing sequence.
Iteration and indexing (subscription) have independent configuration flags
to enable them. They are enabled by default at the same level that
collections.deque is enabled (the extra features level).
Also add tests for checking new behavior.

This updates the berkeley-db-1.xx submodule URL to a repository hosted
under the micropython organisation, and makes the following changes:
- Moves the berkeley-db header files to a single directory within the
submodule, and references all these headers with a much fuller path,
which prevents symbol clashes (eg with esp32 and queue.h).
- Removes unused/non-working files from berkeley-db, which removes all
symlinks in that repo (symlinks don't play well under Windows).
- Allows injecting an external configuration header into berkeley-db, so
the configuration doesn't have to be provided by -Dxx=yy flags to the
compiler (and possibly clashing with other symbols).
- Removes the advertising clause from the BSD 4-clause license of
berkeley-db (see relevant commit and README.Impt.License.Change for
details).
