gdbstub: Use specific MMU index when probing MTE addresses
Use cpu_mmu_index() to determine the specific translation regime (MMU
index) before probing addresses using allocation_tag_mem_probe().
Currently, the MMU index is hardcoded to 0 and only works for user mode.
By obtaining the specific MMU index according to the translation regime,
future use of the stubs relying on allocation_tag_mem_probe in other
regimes will be possible, like in EL1.
This commit also changes the ptr_size value passed to
allocation_tag_mem_probe() from 8 to 1. The ptr_size parameter actually
represents the number of bytes in the memory access (which can be as
small as 1 byte), rather than the number of bits used in the address
space pointed to by ptr.
