Trevor Gross 51c5f191de 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-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.
