exec: Make cpu_memory_rw_debug() target agnostic

cpu_memory_rw_debug() is declared in "exec/cpu-all.h" which
contains target-specific declarations. To be able to use it
from target agnostic source, move the declaration to the
generic "exec/cpu-common.h" header.

Replace the target-specific 'target_ulong' type by 'vaddr'
which better reflects the argument type, and is target agnostic.
