AArch64: Add UNSPECV_PATCHABLE_AREA [PR98776]
Currently patchable area is at the wrong place on AArch64. It is placed
immediately after function label, before .cfi_startproc. This patch
adds UNSPECV_PATCHABLE_AREA for pseudo patchable area instruction and
modifies aarch64_print_patchable_function_entry to avoid placing
patchable area before .cfi_startproc.
