Move aarch64 CIE code to aarch64 backend
This commit moves all aarch64-specific code to deal with CIE structure
introduced in 3a67e1a6b4430374f3073e51bb19347d4c421cfe from
target-independent files to the aarch64 backend.

binutils/
* dwarf.c (read_cie): Add check for 'B'.
gas/
* config/tc-aarch64.h (enum pointer_auth_key,
tc_fde_entry_extras, tc_cie_entry_extras, tc_fde_entry_init_extra,
tc_output_cie_extra, tc_cie_fde_equivalent_extra,
tc_cie_entry_init_extra): Define.
* dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.
(alloc_fde_entry, select_cie_for_fde): Add tc_fde_entry_init_extra
invocation.
(output_cie): Add tc_output_cie_extra invocation.
(select_cie_for_fde): Add tc_cie_fde_equivalent_extra invocation.
* dw2gencfi.h (enum pointer_auth_key): Move to config/tc-aarch64.h.
(struct fde_entry): Add tc_fde_entry_extras invocation
