This adds named-pins support to the esp32 port, following other ports.
Since the name of esp32 CPU pins is just GPIOx, where x is an integer, the
Pin.cpu dict is not supported and CPU pins are just retrieved via their
existing integer "name" (the cost of adding Pin.cpu is about 800 bytes,
mostly due to the additional qstrs).
What this commit supports is the Pin.board dict and constructing a pin by
names given by a board. These names are defined in a pins.csv file at the
board level. If no such file exists then Pin.board exists but is empty.
As part of this commit, pin and pin IRQ objects are optimised to reduce
their size in flash (by removing their gpio_num_t entry). The net change
in firmware size for this commit is about -132 bytes.

The new machine_pin_find() function accepts a Pin object and a integer
object as input and returns a pin object. That can be extended later to
accept a string object, once named pins are supported.

This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also
cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3,
and C3).
Support for IDF v4 is dropped because it's a lot of effort to maintain both
versions at the same time.
The following components have been verified to work on the various SoCs:
ESP32 ESP32-S2 ESP32-S3 ESP32-C3

Set the size of machine_pin_irq_handler array to GPIO_NUM_MAX:
- Min GPIO_NUM_MAX is 22 for IDF_TARGET_ESP32C3.
- Max GPIO_NUM_MAX is 49 for IDF_TARGET_ESP32S3.
The MP_REGISTER_ROOT_POINTER entry must be hard-coded, because the location
that it's evaluated by the compiler does not include the relevant IDF
header to get a definition of GPIO_NUM_MAX.
Instead of being an explicit field, it's now a slot like all the other
methods.
This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

This IO was enabled in IDF commit 68f8b999bb69563f2f3d1d897bc073968f41f3bf,

For ESP32-S3 configurations, CONFIG_SPIRAM_MODE_OCT requires pins 33-37 for
PSRAM. So exclude them from the machine_pin_type and machine_pin_irq_type
object tables.
The current pull=Pin.PULL_HOLD argument doesn't make a lot of sense in the
context of what it actually does vs what the ESP32 quickref document says
it does.
This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init(). Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.
Fixes issue #8283, and see also #8284.
Add a new board type for ESP32-C3 revision 3 and up that implement the USB
serial/JTAG port on pin 18 and 19. This variant uses the USB serial for
programming and console, leaving the UART free.
- Pins 18 and 19 are correctly reserved for this variant. Also pins 14-17
are reserved for flash for any ESP32-C3 so they can't be reconfigured
anymore to crash the system.
- Added usb_serial_jtag.c and .h to implement this interface.
- Interface was tested to work correctly together with webrepl.
- Interface was tested to work correctly when sending and receiving
large files with ampy.
- Disconnecting terminal or USB will not hang the system when it's
trying to print.
Improvements made:
- PSRAM support for S2
- partition definition for 16MiB flash
- correct ADC and DAC pins
- correct GPIO and IRQ pins
- S3 components in CMakeLists

Commit 8a917ad252 added the gpio_reset_pin()
call to make sure that pins that were used as ADC inputs could subsequently
be used as digital IO. But calling gpio_reset_pin() will enable the
pull-up on the pin and so pull it high for a brief period. Instead use
rtc_gpio_deinit() which will just reconfigure the pin as a digital IO and
do nothing else.
Fixes issue #7079 (see also #5771).

For gpio_hold_en() to work properly (not draw additional current) pull
up/down must be disabled when hold is enabled. This patch makes sure this
is the case by reworking the pull constants to be a bit mask.
Previously specifying None as the pull value would leave the pull up/down
state unchanged. This change makes it so -1 leaves the state unchanged and
None makes the pin float, as per the docs.
ISR's no longer need to be in iRAM, and the ESP IDF provides an option to
specify that they are in iRAM if an application needs lower latency when
handling them. But we don't use this feature for user interrupts: both
timer and gpio ISR routines are registered without the ESP_INTR_FLAG_IRAM
option, and so the scheduling code no longer needs to be in iRAM.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.
This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.

Code lineage:
I started by copying the esp8266 machine_pwm.c. I used information from the
ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
sample ledc example code (but I did not copy that code, just studied it to
understand the SDK's API for PWM). So aside from the code copied from the
esp8266 PWM support, everything else you see is just new code I wrote.
I wasn't an employee of anybody when I wrote it, and I wrote it with the
understanding and intention that it's simply a derivative work of the
existing micropython code. I freely and willingly contribute it to the
project and intend that it not change the legal status of the micropython
code base in any way, even if it is included in that base in whole or part.
