This fixes test failures when advancing bootstrap.
When a language feature has UNSTABLE_FEATURE kind, enabling it causes
the compiler to mark the compiled library with the pre-release flag.
JsAllowImplementingFunctionInterface feature is enabled by default in
Wasm backend. So effectively, all Wasm klibs are marked with the
pre-release flag, including the standard library.
Pre-release checks were enabled recently and cause compiler errors.
To fix the problem, this commit changes the feature kind to OTHER, which
doesn't enforce the pre-release flag.
