fix(cpufeat): improve xpaci wrapper

Older toolchains seem to have trouble parsing a directive on the same
line as an instruction, so they choke on the separating semicolon:

/tmp/ccBwXW8I.s:93: Error: unknown architecture `armv8.3-a;'

Put the .arch directive on a line of its own, so that the assembler can
digest it.

Drop the comment on the way: xpaci is a FEAT_PAUTH instruction not
encoded in the hint space, so *every* toolchain needs to be allowed
ARMv8.3 level instructions, not just older ones.

Also we do not need to force x0 as the register, the compiler will pick
it automatically, so drop the register variable.
