gdb: Introduce is_address_tagged target hook
This commit introduces a new target hook, target_is_address_tagged,
which is used instead of the gdbarch_tagged_address_p gdbarch hook in
the upper layer (printcmd.c).
This change enables easy specialization of memory tagging address
check per target in the future. As target_is_address_tagged continues
to utilize the gdbarch_tagged_address_p hook, there is no change in
behavior for all the targets that use the new target hook (i.e., the
remote.c, aarch64-linux-nat.c, and corelow.c targets).
Just the gdbarch_tagged_address_p signature is changed for convenience,
since target_is_address_tagged takes the address to be checked as a
CORE_ADDR type.
