pcsx2|utilities: Remove ambiguous wxString-related overloads

Avoid some function overloads that can accept char*, wxChar* and
wxString as a parameter. wxString can be constructed with either of
those parameters, so the function overloads may actually result in
ambiguity errors. Keep the wxString parameter versions and remove the
rest.

Fixes some compile errors on FreeBSD.
