[roll third_party/pigweed] pw_cpu_exception_cortex_m: Provide ARMv8-M specific build rules

Sets up the initial build framework to support ARMv8-M specific
capability in a way which supports re-using the existing ARMv7-M
code.

Also extends the pw_add_module_library to add PUBLIC_DEFINES and
PRIVATE_DEFINES in order to set the defines to re-use the same
source code.
