edid-decode: improve GTF/CVT checks
1) Warn if a 1.4 EDID supports GTF instead of CVT (GTF is deprecated)
2) If a 1.4 EDID only supports GTF, then do not report Standard Timings
as CVT.
3) Drop the check that GTF and/or CVT support must be present if an
explicit GTF or CVT timing is supported: GTF/CVT support indicates
that any GTF/CVT timings within the Display Range Limits is accepted,
but explicitly indicated GTF/CVT timings are always assumed to be
supported as discrete timings.
