ada: Update personality function for CHERI purecap
This makes two changes to the GNAT personality function to reflect
differences for pure capability CHERI/Morello. The first is to use
__builtin_code_address_from_pointer to drop the LSB from Morello
code pointers when searching through call-site tables (without this
we would never find the right landing pad when unwinding).
The second change is to reflect the change in the exception table
format for pure-capability Morello where the landing pad is a capability
indirected by an offset in the call-site table.
