Convert the mimxrt port from the old `MICROPY_EVENT_POLL_HOOK` macro to use
the new `mp_event_wait_xxx()` functions in conjunction with
`MICROPY_INTERNAL_WFE`.
This change should be functionally equivalent to the existing behaivour
because `mp_event_wait_ms()` and `mp_event_wait_indefinite()` are equal to
`mp_handle_pending(MP_HANDLE_PENDING_CALLBACKS_AND_EXCEPTIONS); __WFE()`,
which is what `MICROPY_EVENT_POLL_HOOK` was.

These classes are based on the Quadrature Encoder blocks of the i.MXRT
MCUs. The i.MXRT 102x has two encoders, the other ones four. The i.MXRT
101x does not support this function. It is implemented as two classes,
Encoder and Counter.
The number of pins that can be uses as inputs is limited by the MCU
architecture and the board schematics. The Encoder class supports:
- Defining the module.
- Defining the input pins.
- Defining a pin for an index signal.
- Defining a pin for a reset signal.
- Defining an output pin showing the compare match signal.
- Setting the number of cycles per revolution (min/max).
- Setting the initial value for the position.
- Setting the counting direction.
- Setting a glitch filter.
- Defining callbacks for getting to a specific position, overrun and
underrun (starting the next revolution). These callbacks can be hard
interrupts to ensure short latency.
The encoder counts all phases of a cycle. The span for the position is
2**32, for the revolution is 2**16. The highest input frequency is
CPU-Clock/24. Note that the "phases" argument is emulated at the API
level (the hardware will always count all phases).
The Counter mode counts single pulses on input A of the Encoder. The
configuration supports:
- Defining the module.
- Defining the input pin.
- Defining the counting direction, either fixed or controlled by the level
of an input pin.
- Defining a pin for an index signal.
- Defining an output pin showing the compare match signal.
- Setting the counter value.
- Setting the glitch filter.
- Defining a callback which is called at a certain value.
- Settings for MIMXRT1015. The MIMXRT1015 MCU has only one encoder/counter
unit.
The counting range is 0 - 2**32-1 and a 16 bit overrun counter. The
highest input frequency is CPU-Clock/12.
The implementation of the `.irq()` method uses the common code from
`shared/runtime/mpirq.c`, including the `irq().flags()` and
`irq().trigger()` methods.

This adds support for the ALT11 alternate function mode on MIMXRT1176
MCUs, enabling FLEXPWM channels on GPIO_AD pins that were previously
unavailable for PWM use.
Changes:
- Add PIN_AF_MODE_ALT11 enum to pin.h
- Add ALT11 column to MIMXRT1176_af.csv with FLEXPWM mappings
- Enables FLEXPWM1-4 on GPIO_AD_06 through GPIO_AD_21
This change only affects MIMXRT1176-based boards (MIMXRT1170_EVK and
PHYBOARD_RT1170). Other MIMXRT family chips use alternate function
modes ALT0-ALT9 and are not affected.
Tested on MIMXRT1176 hardware with PWM output on GPIO_AD_14
(FLEXPWM3_PWM0_X).

The rt117x uses the LPADC peripheral which supports both A-side and B-side
channel inputs, e.g. ADC1_CH1A and ADC1_CH1B.
Previously, only `kLPADC_SampleChannelSingleEndSideA` was being used during
capture, while the pin may be in side B. The fix in this commit detects
the side based on the pin configuration and sets `sampleChannelMode`
appropriately.

The default size for the ROM partition is 256k, and it is placed in flash
between the text and writable vfs sections. Its size can be changed in
`mpconfigboard.mk` by defining `MICROPY_HW_ROMFS_BYTES` to a different
value, but it must not be smaller than a single sector.
The MIMXRT1170_EVK and SEEED ARCH MIX ROMFS boards use a larger size of
512kB. ROMFS support is disabled for MIMXRT1050_EVKB due to issues with
Hyperflash.
The extents of the ROM partition are defined by the linker-level symbols
`_micropy_hw_romfs_part0_start` and `_micropy_hw_romfs_part0_size`,
following existing ports.

The functionality is similar to the RP2 implementation. The supported
address size is 7 bit. In order to achieve a sufficient response, the
target I2C IRQ handler has to run from RAM, causing much more code moved to
RAM than required.
Tested with Teensy 4.1, MIMXRT1021EVK, MIMXRT1011EVK and MIMXRT1170, using
both a On-Board SoftI2C as controller and a RP2 Pico as external
controller.

Allowing to use e.g. the Adafruit bootloaders with MicroPython. The .uf2
file is created in addition to the .bin and .hex files allowing to use the
latter ones without the bootloader for debugging and testing.
Changes:
- Set the location of the ISR Vector and .text segment to 0x6000C000 and
0x6000C400.
- Reserve an area at the start of ITCM for a copy of the interrupt vector
table and copy the table on reset to this place.
- Extend `machine.bootloader()` by setting the magic number to enable the
bootloader on reset.
- Create a .uf2 file which skips the segments below 0x6000C000.
The bootloader has to be installed as a preparation step using the board
specific methods, but then the firmware's .uf2 file version can be
installed using the bootloader. The bootloader can be invoked with:
- double reset
- calling machine.bootloader()
- Using the touch1200 method
Double reset is hard to achieve on MIMXRT boards, since there is no clean
reset pin. Some MIMXRT boards provide it by switching the power.
Some boards are excluded from the .uf2 build:
- MIMXRT1050_EVK: The uf2 bootloader is built for the QSPI version of the
board. MicroPython supports the Hyperflash version.
- MIMXRT1176_EVK: No support for this board yet, but it should be possible.

In CMSIS 5.9.0, the compiler headers define `__VECTOR_TABLE`, which will be
substituted with its corresponding value (e.g., `__Vectors` for gcc).
However, the linker script in this port can't include compiler headers when
it's processed, so `__VECTOR_TABLE` is used as the literal variable name,
which results in an undefined linker error.
To fix this, the two possible values of `__VECTOR_TABLE` are both defined
in the linker script.

All ports now use `--board-csv`, `--prefix`, `--output-souce`,
`--output-header` and no longer write to stdout. This matches the esp32
implementation.
Ports that have an AF input use `--af-csv` (to match `--board-csv`).
Any additional output files are now prefixed with `output-` (e.g.
`--output-af-const`).
Default arguments are removed (all makefiles should always specify all
arguments, using default values is likely an error).
Replaced the `af-defs-cmp-strings` and `hdr-obj-decls` args for stm32 with
just `mboot-mode`. Previously they were set on the regular build, now the
logic is reversed so mboot sets it.
