Fix #77954.

* expression.cs (Invocation.IsApplicable): Ensure a generic method
definition doesn't take part in overload resolution.
(Invocation.IsParamsMethodApplicable): Likewise.
(Invocation.OverloadResolve): When replacing a reflected override
method with its base definition, ensure that type arguments are applied.
