feat(debug): add helpers for aborts on AARCH32
New helper functions are created to handle data & prefetch aborts
in AARCH32. They call platform functions, just like what
report_exception is doing.
As extended MSR/MRS instructions (to access lr_abt in monitor mode)
are only available if CPU (Armv7) has virtualization extension,
the functions branch to original report_exception handlers if this is
not the case.
Those new helpers are created mainly to distinguish data and prefetch
aborts, as they both share the same mode.
This adds 40 bytes of code.
