Changes are:
- Run ADC on PCLK/16.
- Verify and optimize timings (ADC_STAB_DELAY_US, ADC_SAMPLETIME_DEFAULT).
- Add support for STM32H5 VBAT and COREVDD channels on ADC2.
- Replace ADC constants in machine_adc_locals_dict_table.
- Convert STM32 literal to channel numbers in adc_config_channel with
corresponding STM32 LL library functions (__LL_ADC_IS_CHANNEL_INTERNAL(),
__LL_ADC_CHANNEL_TO_DECIMAL_NB()).
Reasoning for the second last point: the STM32 driver literals are uint32_t
that don't work with MP_ROM_INT() which handles signed 31 bit integers
only. Introduce enumerator machine_adc_internal_ch_t to define external
channels (0..19), internal channels (256..) and the special channel VREF
(0xffff). Values are converted to STM32 literals with adc_ll_channel()
when required in adc_config_and_read_u16().

Fixed the preliminary STM32H5 ADC support for pyb.ADC:
- Run ADC on PCLK/16.
- Use STM32 ADC library channel literals (__HAL_ADC_DECIMAL_NB_TO_CHANNEL).
- Use correct temperature conversion for H5 (30C, 130C calibration points).

To simulate a partial erase, the code reads a native block, erases it,
and writes back the data before and after the erased area. However, the
current logic was filling the area after the erased block with data
from the beginning of the native block-aligned data, instead of applying
the proper offset.
Fixes#12474.

Currently, check_esp_err() raises an exception without a location in the
source code, eg:
Traceback (most recent call last):

This commit allows additional error reporting (function, line and file) to
be enabled via detailed exceptions. Change the error reporting config to
#define MICROPY_ERROR_REPORTING (MICROPY_ERROR_REPORTING_DETAILED)
and then exception messages from IDF errors look like:

Fixes are:
- The baudrate argument is a keyword arg, it was passed before as a
positional arg.
- Use the port and baudrate arguments passed from higher level code instead
of the hard-coded port ID and baudrate, which would allow HCI drivers to
change baudrates.
- Increase UART char timeout and RX buffer size.

.. and switch makerfabs tft7 over to it as a test.
We have our existing way of "reserving" PSRAM for esp-idf (we actually
control it all but add back the "reserved" part). However, this does
not work with off the shelf esp_lcd, which only will allocate a
framebuffer in PSRAM if CONFIG_SPIRAM_USE_CAPS_ALLOC (or CONFIG_SPIRAM_USE_ALLOC)
is defined, not if CONFIG_SPIRAM_USE_MEMMAP is.
This new way is possibly compatible with more esp-idf code, but it complicates
CircuitPython's initial startup since nothing until port_heap_init is
permitted to use the CP heap or supervisor allocator. In practice this
seems to be OK today.
Right now this doesn't change the setting across all boards with PSRAM and so
it does not revert esp-idf to its prior state. Instead, what I'm thinking is
that we can do it during or just after the IDF5 update when sdkconfig files
will be getting an overhaul anyway.
With DEBUG build and a consle UART, this would occur early during startup on makerfabs tft7:
```

In CPython, `_thread.start_new_thread()` returns an ID that is the same ID
that is returned by `_thread.get_ident()`. The current MicroPython
implementation of `_thread.start_new_thread()` always returns `None`.
This modifies the required functions to return a value. The native thread
id is returned since this can be used for interop with other functions, for
example, `pthread_kill()` on *nix. `_thread.get_ident()` is also modified
to return the native thread id so that the values match and avoids the need
for a separate `native_id` attribute.

CONFIG_USB_OTG_SUPPORTED is automatically set by the ESP-IDF when the chip
supports USB-OTG, which is the case for the ESP32-S2 and ESP32-S3.
When trying to use the JTAG console with these chips, it would not work
because our USB implementation will take over control over the USB port,
breaking the JTAG console in the process.
Thus, when the board is configured to use the JTAG console, we should not
enable our USB console support.
Additionally, this change also frees up UART0 when an USB-based console is
configured, since there's no reason to prevent (re)configuration of UART0
for other uses in that case.

This implements support for SO_BINDTODEVICE, which allows telling a socket
to use a specific interface instead of lwIP automatically selecting one.
This allows devices that have multiple connections (for example cellular
over PPP in addition to WLAN) to explicitly choose which data is send over
which connection, which may have different reliability and or (mobile data)
costs associated with using them.
The used lwIP network stack already has support for this, so all that was
needed was to expose this functionality in MicroPython. This commit
exposes a new constant SO_BINDTODEVICE which can be set as an socket
option. As a value it expects the name of the interface to bind to. These
names can be retrieved using `.config('ifname')` implemented on each
interface type (including adding in this commit a `.config()` method to
PPP, which it didn't have before), which returns a string with the
interface name:
>>> import machine
>>> import network
>>> network.WLAN(network.AP_IF).config('ifname')
'lo0'
>>> wlan = network.WLAN(network.AP_IF)
>>> wlan.active(True) and wlan.config('ifname')
'ap1'
>>> wlan = network.WLAN(network.STA_IF)
>>> wlan.active(True) and wlan.config('ifname')
'st1'
>>> ppp = network.PPP(machine.UART(0))
>>> ppp.active(True) and ppp.config('ifname')
'pp1'
>>> ppp = network.PPP(machine.UART(0))
>>> ppp.active(True) and ppp.config('ifname')
'pp2'
>>> ppp = network.PPP(machine.UART(0))
>>> ppp.active(True) and ppp.config('ifname')
'pp3'
Note that lo0 seems to be returned by lwIP if the interface is not yet
active. The method can also return None in the case of PPP where the
entire lwIP interface doesn't yet exist before being activated. Currently
no effort is made to unify those cases; it is expected that whatever we
receive from lwIP is valid.
When the socket option is set, this forces using a specific device:
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BINDTODEVICE, 'st1')
setsockopt will throw (OSError: [Errno 19] ENODEV) if the specified
interface does not exist.
Tested with LAN, WLAN, and PPP; can specify which interface should be used
and when testing with, for example, HTTP requests to ifconfig.co the
returned IP address confirms a specific interface was used.
