[compiler] Allow nonreactive stable types as extraneous deps

When checking ValidateExhaustiveDeps internally, this seems to be the most common case that it flags. The current exhaustive-deps rule allows extraneous deps if they are a set of stable types. So here we reuse our existing isStableType() util in the compiler to allow this case.
