Pierre-Clément Tosi 7a928b32f1 arm64: Introduce esr_brk_comment, esr_is_cfi_brk ...

As it is already used in two places, move esr_comment() to a header for
re-use, with a clearer name.

Introduce esr_is_cfi_brk() to detect kCFI BRK syndromes, currently used
by early_brk64() but soon to also be used by hypervisor code.
