Add CONFIG_CRC for building CRC related routines.
CRC routines are now being built for each application, whether used or
not and are add in the build system unconditionally.
Keep CONFIG_CRC enabled by default for now and until all users have

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

The VREFINT and TEMPSENSOR internal channels have a stabilization time
after they are enabled. Right now this just causes the first measure to
be a bit off, however with PR #47691 which stops the internal channels
after each readout, this is something important to respect. Fortunately
the stabilization time is available as constants in the HAL, so just
wait the time specified by the constants.
Note that the VBAT internal channel does not have any stabilization
time.

This commit avoid re-enabling the ADC,
because this starts conversion.
According to the RefMan (RM0008) of the stm32F10x mcu,
enabling the ADC will start the conversion
if the ADC is already enabled. "Conversion starts when
this bit holds a value of 1 and a 1 is written to it."
That's not what we want.

Allow the battery voltage to be read through the ADC even if the
CONFIG_STM32_VBAT driver is not enabled.
I guessed this part of code is conditionally compiled depending on
CONFIG_STM32_VBAT because this feature, and hence the
LL_ADC_CHANNEL_VBAT constant is not available on all families. As the
feature is already checked at runtime (as the same driver supports
multiple instances), we can conditionally compile it depending on
LL_ADC_CHANNEL_VBAT instead.
