core/cortex-m[0]: Remove C++ exception unwind stubs
These symbols should only be needed for unwinding C++ exceptions:
https://sourceware.org/binutils/docs/as/ARM-Unwinding-Tutorial.html
It's unclear why these are here since we're not compiling with C++ at
this point. The code was introduced in commit
e24fa592d2a215d8ae67917c1d89e68cdf847a03, which doesn't provide any
details.
Once we start compiling C++, these definitions cause problems since they
conflict with the real symbols in libunwind.
