The standard Zephyr console implementation doesn't make use of
`tty_set_rx_timeout()` and therefore all the functions to receive
characters block indefinitely until data is received (including
`console_read()`).
This commit also releases the GIL where it applies, e.g. the REPL and the
time sleep functions.

This commit implements the `_thread` module on the zephyr port.
Due to the fact that we are still using a rather old version of Zephyr,
`CONFIG_DYNAMIC_THREAD` is not available and therefore the stack for
threads cannot be allocated dynamically, only at compile time. So for the
time being and for the purpose of this commit, a maximum of 4 Zephyr
threads (besides the main thread) can be created. Once we manage to update
to the latest version of Zephyr this won't be a problem anymore.
Configuration for the nrf52840dk is added as part of this change, because
this board was used to test the threading support.
The Zephyr option `CONFIG_THREAD_CUSTOM_DATA` is used to enable threading
on a per board basis. The `thread.conf` file is added as a convenient way
to enable threading.

Do NOT use `mp_hal_delay_us()` for short delays. This was initially done
to make short delays precise, but it does not allow for scheduling. Leave
using `mp_hal_delay_us()` to user code if needed.

The upper 32 bit of the 64 bit ticks register was taken before disabling
the interrupts. That may have caused a wrong return values. Besides that,
the function may cause trouble when called in an IRQ context, because it
unconditionally enables IRQ.

As reported in #14430 the Xtensa compiler can add R_XTENSA_ASM_EXPAND
relocation relaxation entries in object files, and they were not
supported by mpy_ld.
This commit adds handling for that entry, doing nothing with it, as it
is only of real use for an optimising linker.

The printed type for stdio streams indicates "FileIO", which is a binary IO
stream. Stdio is not binary by design, and its printed type should
indicate a text stream. "TextIOWrapper" suits that purpose, and is used
by VfsPosix files.

Currently both the qemu-arm and qemu-riscv ports share a lot of code and
functionality. This commit merges the qemu-riscv port into the qemu-arm
port. The only real differences between the two are the toolchains used to
build the code, and the initialisation/startup framework. Everything else
is pretty much the same, so this brings the following benefits:
- less code duplication
- less burden on maintenance
- generalised qemu port, could in the future support other architectures
A new board `VIRT_RV32` has been added to the qemu-arm port which is the
existing RISC-V board from the qemu-riscv port. To build it:
$ make BOARD=VIRT_RV32 repl
To cleanly separate the code for the different architectures, startup code
has been moved to ports/qemu-arm/mcu/<arch>/.

Now that some ports support multiple architectures (eg esp32 has both
Xtensa and RISC-V CPUs) it's no longer possible to set mpy-cross flags
based on the target, eg `./run-tests.py --target esp32`. Instead this
commit makes it so the `-march=xxx` argument to mpy-cross is detected
automatically via evaluation of `sys.implementation._mpy`.

This fixes issue of ESP32-S3 switching its config over to USB serial/JTAG
instead of native USB.
The the existing logic was hard to follow, adding this config macro makes
it easier to see which USB is in use and to have board definitions that
enable/disable different USB levels.
This commit also drops (nominal) support for manually setting
CONFIG_ESP_CONSOLE_USB_CDC in sdkconfig. No included board configs use this
and it didn't seem to work (if secondary console was set to the default USB
Serial/JTAG then there is no serial output on any port, and if secondary
console was set to None then linking fails.) Can be re-added if there's a
use case for it.

This allows UART RX to function while flash erase/writes operations are
under way, preventing lost serial data so long as it fits in the UART RX
buffer.
This enables (among other things) mpremote to successfully copy files to
boards that use a UART REPL.
Enable via the following option placed in `mpconfigboard.mk`:
MICROPY_HW_ENABLE_ISR_UART_FLASH_FUNCS_IN_RAM = 1

This commit adds a new `network.PPP` interface which works on any port that
has bare-metal lwIP, eg rp2, stm32, mimxrt.
It has been tested on stm32. A board needs to enable
`MICROPY_PY_NETWORK_PPP_LWIP` and then it can use it as follows:
import network
ppp = network.PPP(uart)
ppp.connect()
while not ppp.isconnected():
pass
# use `socket` module as usual, etc
ppp.disconnect()
Usually the application must first configure the cellular/etc UART link to
get it connected and in to PPP mode first (eg ATD*99#), before handing over
control to `network.PPP`.
The PPP interface automatically configures the UART IRQ callback to call
PPP.poll() on incoming data.

These all require hardware connections, so live in a different directory.
Except for the IRQ_BREAK test of ESP32 devices a single UART with loopback
is sufficient.
General:
SAMD21: Due to the limited flash size only SAMD21 devices with external
flash support uart.irq().
IRQ_BREAK:
ESP32 needs different UART devices for creating and sensing a break.
Lacking a second UART the test is skipped for ESP32S2 and ESP32C3. RP2
does not pass the test reliable at 115200 baud, reason to be found.
Thus the upper limit is set to 57600 Baud.
Coverage:
esp32 pass when different UART devices are used.
rp2 pass up to 57600 baud
IRQ_RX:
SAMD21: Being a slow device it needs data to be sent byte-by-byte at
9600 baud, since the IRQ callback is scheduled delayed and then the
flags do not match any more. The data matches since it is queued in
the FIFO resp. ringbuffer.
CC3200: The test cannot be performed since no calls are accepted in the
IRQ handler like u.read(). Skipped.
Coverage:
cc3200 fail due to major differences in the implementation.
esp32 pass
nrf pass
renesas-ra pass
samd pass see the notes.
stm32 pass
IRQ_RXIDLE:
STM32: With PyBoard the IRQ is called several times, but only once with
the flag IRQ_RXIDLE set.
Coverage:
esp32 pass
mimxrt pass
renesas-ra pass
rp2 pass
samd pass for both SAMD21 and SAMD51
stm32 fail. see notes.

The UART.IRQ_IDLE callback is called about two character times after the
last byte, or 1 ms, whichever is larger. For the irq, timer 0 is used.

Allowing to define the trigger UART.IRQ_RXIDLE as well as UART.IRQ_RX. The

With the softtimer the minimal delay between the end of a message and the
trigger is 2 ms. For baud rates <= 9600 baud it's three character times.
Tested with baud rates up tp 115200 baud. The timer used for RXIDLE is
running only during UART receive, saving execution cycles when the timer is
not needed.
The irq.flags() value is changed only with an expected event. Do not
change it otherwise.
