Add reset causes for temperature (e.g. overheating), hardware faults
and a user initiated reset.

Add `hwinfo_get_reset_cause` and `hwinfo_clear_reset_cause` to retrieve
and to clear cause of system reset on supported platforms.
Different platforms can provide different causes of reset, however
there is a great deal of overlap. `enum reset_cause` can be expanded in
the future to support additional reasons, as additional platforms are
supported.

HWINFO drivers should be responsible for ensuring that
the data structure is a sequence of bytes. That is not
what the current sam0 and nordic drivers do. The drivers
read the data as u32_t and then memcpy the data to a
buffer. This ensures the data has the endianness of the
underlying MCU, which in this case is Cortex M0 which
is little endian.
This commit fixes the endianness so the data can be
interpreted as a "left to right sequence of bytes".
This commit updates the API doc to provide clarification
of the data structure.
Add to 2.3 release notes.
Fixes#23444, #24103

move hwinfo.h to drivers/hwinfo.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
