This provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.
This class can be used directly, and also can be used from Python to
implement (via io.BytesIO) zlib.decompress and zlib.compress, as well as
gzip.GzipFile.
Enable/disable this on all ports/boards that zlib was previously configured
for.

There are enough places that implement __exit__ by forwarding directly to
mp_stream_close that this saves code size.
For the cases where __exit__ is a no-op, additionally make their
MP_STREAM_CLOSE ioctl handled as a no-op.

The existing qspi for stm32 implementation can only send a spi command with
exactly 0 or 2 data bytes. Certain spiflash chips (e.g. AT25SF321B) have
commands that only take a single data byte, and will ignore the command if
more than that is sent. This commit allows sending a command with a single
data byte.

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.
