Support overloaded test methods in CompileWithTargetClassAccessExtension

Prior to this commit, CompileWithTargetClassAccessExtension failed to
properly select overloaded test methods because it ignored the method
parameter list when looking up the test method.

This commit addresses this issue by selecting the test method using its
fully qualified method name which takes in account the class name,
method name, and parameter names.

Closes gh-28901
