For STM32G4, there is a errata on ADC that may get wrong ADC result.
According to the errata sheet, this can be avoid by performing two
consecutive ADC conversions and keep second result.

For STM32G4 series, the internal sensors are connected to:
- ADC1_IN16: Temperature sensor
- ADC1_IN17: Battery voltage monitoring
- ADC1_IN18: Internal voltage reference
but ADC_CHANNEL_TEMPSENSOR_ADC1, ADC_CHANNEL_VBAT,
ADC_CHANNEL_VREFINT are not defined as 16, 17, 18.

This commit converts channel 16, 17, 18 to ADC_CHANNEL_x in
adc_get_internal_channel().

For STM32G4, ADC clock frequency should be equal or less than 60MHz.
To satisfy this specification, ADC clock prescaler should be equal or
greater than 4 (For example, NUCLEO_G474RE runs 170MHz).

In addition, to obtain accurate internal channel value,
the ADC clock prescaler is set to 16 because vbat needs at least 12us
(16/170*247.5=23.3us).

For STMG4 MCUs, the peripheral registers for DAC have to be accessed by
words (32bits) because DAC is connected to AHB directly.

(This requirement is also there for other MCU series.  However, if DAC is
connected to APB like F4/L1/L4 MCUs, AHB byte or half-word transfer is
changed into a 32-bit APB transfer.  This means that PSIZE does not have to
be DMA_PDATAALIGN_WORD on these MCUs, and in fact must be BYTE/HALFWORD to
function correctly.)

Fixes issue #9563.

This board requires slightly different configuration to work.  It is
important to hard reset (cycle power) if you try to initialize LAN and it
fails, before trying again with new parameters.

This is a fix for commit bccbaa92:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
  interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
  interface is set active(True) and it was previously inactive, ie. not
  only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

This commit adds the SSLContext class to the ssl module, and retains the
existing ssl.wrap_socket() function to maintain backwards compatibility.

CPython deprecated the ssl.wrap_socket() function since CPython 3.7 and
instead one should use ssl.SSLContext().wrap_socket().  This commit makes
that possible.

For the axtls implementation:
- ssl.SSLContext is added, although it doesn't hold much state because
  axtls requires calling ssl_ctx_new() for each new socket
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added

For the mbedtls implementation:
- ssl.SSLContext is added, and holds most of the mbedtls state
- ssl.verify_mode is added (getter and setter)
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added

The signatures match CPython:
- SSLContext(protocol)
- SSLContext.wrap_socket(sock, *, server_side=False,
    do_handshake_on_connect=True, server_hostname=None)

The existing ssl.wrap_socket() functions retain their existing signature.

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:
