9130: Prefix/suffix parameter inlay hint hiding heuristic is more strict r=Veykril a=Veykril

Instead of just plainly checking prefix/suffix of the argument string to the parameter name we only check for prefixes and suffixes if they are split apart via an underscore meaning, with the argument `foo`, it will be hidden for the parameter name `foo_bar` but not for `foobar`.
