Moving some code in common to be able to manage several ADC instances,
or several channels of an instance.
The change involves:
- moving dac_s structure definition to common_object.h
- create TARGET_STM/analogout_api.c and move fully common analog_out
functions in there
- rename analogout_api.c of each target family into analogout_device.c
to keep platform specific code
- update analogout_device.c to rely on obj->handle and obj->channel
- align analogout_init function as much as possible between families in
analogout_device.c files
ADC1 channel2 and ADC2 of few targets only have an output switch and no
buffer. This switch needs to be enabled, and also the buffer can be enabled
in order to reduce the output impedance on output, and to drive external
loads directly without having to add an external operational amplifier.
This allows a proper handling of multiple instances. Also this commit
stores the channel in the HAL format so that it can be re-used more easily
and call to HAL are straightforward.
This is as it used to be, reverting the removal. uARM does not have any hook
that we could use for mbed sdk init and copy nvic, therefore _open is used that
should be sufficient, but not ideal.

With default sampling time, the MBED2 and CI test shield tests would fail
because the stabilization slope of ADC is relatively slow.
ERROR (out:0.8000) - (in:0.7407) = (0.0593)
ERROR (out:0.9000) - (in:0.8354) = (0.0646)
ERROR (out:1.0000) - (in:0.9289) = (0.0711)
This is related to the 10kOhms resistors used to connect Ain to
Aout mounted on the CI shileds, and internal capacitance of L0 targets.
If connecting Ain and Aout with wires, bypassing the resistors, the test
is passed. So we're increasing the sampling time to let the automated
ci shiled tests PASS.
OK (out:0.8000) - (in:0.7863) = (0.0137)
OK (out:0.9000) - (in:0.8869) = (0.0131)
OK (out:1.0000) - (in:0.9844) = (0.0156)

This provides the correct binary semaphore behaviour that was expected
by the equeue layer, removes concerns around semaphore overflow, and
reduces the number of spurious wakeups which may save a bit of power.
This also fixes some issues we were seeing around the RTX 5 changes
to semaphore behaviour.
- default value is the same as before patch
- system_stm32f4xx.c file is copied to family level with all other ST cube files
- specific clock configuration is now in a new file: system_clock.c
- nvic_addr.h file is now in TARGET_STM level, and can be used everywhere
The prev-pointer of the running threads mutex list was not set when
multiple mutexes are acquired at a time. This leads to a corrupted list
if the mutexes are not freed in reversed order.

"FAMILY_STM32" has been creeated with all common features.
All STM32 devices can now inherit from it.
This will simplify readability and maintainability.
