micropython: bump to 1.23.0 release

Bump micropython to 1.23.0. This is done to fix support for MbedTLS 3.0

Lots changed between 1.21 and 1.23 for the library side.

Mainly the barkeley-db library was moved to micropython own fork and the
cdef patch required lots of changes. (we have to manually include a copy
of cdef.h as it was dropped by them)
Also a new patch is required to mute some compilarion error that are
false-positive. (variable not initialized but that are ALWAYS
initialized)

Also refresh the extmod patch with new files included.
