  Log Message:
  -----------
  [AArch64][COFF] Branch-protection=standard/pac-ret means "b-key" on Windows (#203989)

On AArch64 Windows the `B-key` is the only supported key for userspace,
let's make "standard" and "pac-ret" options generate "b-key".

Fixes: #203852
(cherry picked from commit 68f703f3e58a52c41b39dfc654a675560b6c5614)
