Remove `compiler-builtins-{no-asm,mangled-names}`
Remove `compiler-builtins-no-asm`
This feature used to be for when Cranelift didn't support inline
assembly, but its last uses were removed in 52933e0bd200 ("Don't disable
inline asm usage in compiler-builtins when the cranelift backend is
enabled"). and cba05a7a14b3 ("Support naked functions").
This doesn't remove the feature from the `compiler-builtins` crate, that
will be done separately in the subtree repo.

Remove `compiler-builtins-mangled-names`
This config was added in 207de019dc67 ("libary: Forward
compiler-builtins "asm" and "mangled-names" feature") but it does not
appear this has ever been used. The PR adding it (rust-lang/rust#78472) says that
this was exposed to help with configuration and points at the [Hermit
Cargo config], but as far as I can tell, this feature name has never
been mentioned in that repository's git history.
Thus, clean up a seemingly unneeded feature.
