[PATCH, BINUTILS, AARCH64, 1/9] Add -march=armv8.5-a and related internal feature macros

This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/exploration-tools)

This is the first of the patch series and adds -march=armv8.5-a and
other internal feature marcos needed for it.
