Fix comments about GCC/Clang's enum width for arm-none targets.
GCC uses the `-fshort-enums` ABI for arm-none and the `int`-sized enum ABI for arm-linux. Clang uses the `int`-sized enum ABI for all arm targets. Both options are permitted by AAPCS. Rust is matching GCC's behavior for these targets, as interop with code code compiled by GCC is desirable in the bare-metal context. See #87917.
