Java: `ReflectiveMethodAccess::inferAccessedMethod()` ignores parameters

The Java predicate `ReflectiveMethodAccess::inferAccessedMethod()` only checks the name of the method but ignores the parameters:
https://github.com/github/codeql/blob/04a7ff7f762cd11d9cba0ab864cc6bb909a830c8/java/ql/lib/semmle/code/java/Reflection.qll#L363-L366

This leads to incorrect results when a class declares multiple methods with the same name but different signature.

Start in java/ql/lib/semmle/code/java/Reflection.qll at ReflectiveMethodAccess::inferAccessedMethod(), especially lines 363-366, and read how the predicate identifies methods. Check its behavior against a class with multiple methods sharing a name but having different signatures. Done means the inferred method distinguishes those overloads by their parameters rather than only by name.
