arm: fully validate mem_noofs_operand [PR120351]

It's not enough to just check that a memory operand is of the form
mem(reg); after RA we also need to validate the register being used.
The safest way to do this is to call memory_operand.

PR target/120351

gcc/ChangeLog:

* config/arm/predicates.md (mem_noofs_operand): Also check the op
is a valid memory_operand.

gcc/testsuite/ChangeLog:

* gcc.target/arm/pr120351.c: New test.
