Moves the armv7m implementation of pw_cpu_exception to
pw_cpu_exception_cortex_m since much of the logic can be shared between
ARMv8-M and ARMv7-M. Symbol names are also updated to reflect current
naming style for extern "C" symbols. Old names will be removed in
pwrev/31060.
Warning, symbol renames are breaking!
pw_CpuExceptionEntry -> pw_cpu_exception_Entry
pw_CpuExceptionDefaultHandler -> pw_cpu_exception_DefaultHandler

The pw_cpu_exception facade is comprised of three parts: the part
implemented by the architecture, and the part implemented by the
application, and some supporting libraries that make it easier to dump
CPU state. Since these are provided independently, the facade has been
split into three facades:
1. entry
2. handler
3. support
