Checks are added to ensure, that only one of the flash drivers is selected.

The QSPI driver provides the interface for using an on-board QSPI flash for
the filesystem. It provides the same methods as the driver for the
internal flash and uses the same name. Therefore, only one of the drivers
for internal flash, SPI flash and QSPI flash must be enabled at a time.

The SPI flash driver includes the block device for being used as a

For SAMD21 devices, the board flash signals must be named in pins.csv as
FLASH_MOSI, FLASH_MISO, FLASH_SCK, FLASH_CS for creating the SPI object.
And rename the QSPI pins to QSPI_xxxx instead of FLASH_xxx.

Prior to this commit, importing a module that exists but has a syntax error
or some other problem that happens at import time would result in a
potentially-incomplete module object getting added to sys.modules.
Subsequent imports would use that object, resulting in confusing error
messages that hide the root cause of the problem.
This commit fixes that issue by removing the failed module from sys.modules
using the new NLR callback mechanism.
Note that it is still important to add the module to sys.modules while the
import is happening so that we can support circular imports just like
CPython does.
Fixes issue #967.

The changed functions now use less stack, and don't have any issues with
local variables needing to be declared volatile.
Testing on a PYBv1.0, imports (of .py, .mpy and frozen code) now use 64
less bytes of C stack per import depth.

NLR buffers are usually quite large (use lots of C stack) and expensive to
push and pop. Some of the time they are only needed to perform clean up if
an exception happens, and then they re-raise the exception.
This commit allows optimizing that scenario by introducing a linked-list of
NLR callbacks that are called automatically when an exception is raised.
They are essentially a light-weight NLR handler that can implement a
"finally" block, i.e. clean-up when an exception is raised, or (by passing
`true` to nlr_pop_jump_callback) when execution leaves the scope.

This commit just takes the necessary parts of pyboard.py and merges them
with pyboardextended.py to make a new transport_serial.py, and updates the
rest of mpremote to use this instead.
It is difficult to continue to add features to mpremote (which usually
requires modification to pyboard.py) while also maintaining backwards
compatibility for pyboard.py.
The idea is that this provides a starting point for further refactoring of
mpremote to allow different transports (webrepl, BLE, etc).

For example, the `reset` shortcut previously allowed an optional delay, but
the argument handling cannot handle `reset next-command` as `next-command`
will be interpreted as the delay argument. The fix in this commit allows
`reset + next-command`.

This allows the sequence to be paused (e.g. wait for device, etc).
Also removes the t_ms arg in reset/bootloader, because these arguments
don't really need to be changed, and keeping them would mean inconsistent
units used for time delays.

- Exact matches of built-ins bypass filesystem.
- u-prefix modules can be overridden from the filesystem.

This can lead to duplicate initialisations if a module can be imported
via multiple names, so the module must track this itself anyway.
This reduces code size (diff is -40 bytes), and avoids special treatment of
builtin-modules-with-init with respect to sys.modules. No other builtin
modules get put into sys.modules.

To use this:
- Create a built-in module, and add the module object as a member of the
parent module's globals dict.
- The submodule can set its `__name__` to either `QSTR_foo_dot_bar` or
`QSTR_bar`. The former requires using qstrdefs(port).h to make the qstr.
Because `bar` is a member of `foo`'s globals, it is possible to write
`import foo` and then immediately use `foo.bar` without importing it
explicitly. This means that if `bar` has an `__init__`, it will not be
called in this situation, and for that reason, sub-modules should not have
`__init__` methods. If this is required, then all initalisation for
sub-modules should be done by the top-level module's (i.e. `foo`'s)
`__init__` method.

This makes it so that sub-packages are resolved relative to their parent's
`__path__`, rather than re-resolving each parent's filesystem path.
The previous behavior was that `import foo.bar` would first re-search
`sys.path` for `foo`, then use the resulting path to find `bar`.
For already-loaded and u-prefixed modules, because we no longer need to
build the path from level to level, we no longer unnecessarily search
the filesystem. This should improve startup time.
Explicitly makes the resolving process clear:
- Loaded modules are returned immediately without touching the filesystem.
- Exact-match of builtins are also returned immediately.
- Then the filesystem search happens.
- If that fails, then the weak-link handling is applied.
This maintains the existing behavior: if a user writes `import time` they
will get time.py if it exits, otherwise the built-in utime. Whereas `import
utime` will always return the built-in.
This also fixes a regression from a7fa18c203a241f670f12ab507aa8b349fcd45a1
where we search the filesystem for built-ins. It is now only possible to
override u-prefixed builtins. This will remove a lot of filesystem stats
at startup, as micropython-specific modules (e.g. `pyb`) will no longer
attempt to look at the filesystem.
Added several improvements to the comments and some minor renaming and
refactoring to make it clearer how the import mechanism works. Overall
code size diff is +56 bytes on STM32.

If sys.path is enabled, but empty, this will now no longer search the
filesystem. Previously an empty sys.path was equivalent to having
`sys.path=[""]`. This is a breaking change, but this behavior now matches
CPython.
This also provides an alternative mechanism to the u-prefix to force an
import of a builtin module:
```
import sys
_path = sys.path[:]
sys.path.clear()
import foo # Forces the built-in foo.
sys.path.extend(_path)
del _path
```
Code size diff is -32 bytes on PYBV11.

Three bugs have been fixed in this commit:
1. When the duty was set with duty_u16(), changing the freq with pwm.freq()
would not keep relative duty rate, but the absolute pulse duration.
2. Fix another inconsistency when displaying the PWM pin's properties of a
QTMR channel.
3. Improve the error checks for the second channel being a PWM pin and pin
pairs to be a FLEXPWM A/B pair.
