Add Aarch64 SVE dwarf regnums
This is as per the spec:
https://developer.arm.com/products/architecture/a-profile/docs/100985/0000
gdb/
* aarch64-tdep.c (aarch64_dwarf_reg_to_regnum): Add mappings.
* aarch64-tdep.h (AARCH64_DWARF_SVE_VG): Add define.
(AARCH64_DWARF_SVE_FFR): Likewise.
(AARCH64_DWARF_SVE_P0): Likewise.
(AARCH64_DWARF_SVE_Z0): Likewise.
