[Backport 3.3] [Bug #20085] Use consistent default options for `-mbranch-protection` (#9385)
[Bug #20085] Use consistent default options for `-mbranch-protection`
We need to use the same options for both C compiler and assembler
when `-mbranch-protection` is guessed by configure. Otherwise,
`coroutine/arm64/Context.{h,S}` will use incompatible PAC strategies.
