Although returning wxFONTFAMILY_UNKNOWN when the font family is not recognized
makes more sense, it breaks a lot of existing code including all the
font-related code generated by DialogBlocks, so prefer to return
wxFONTFAMILY_DEFAULT instead -- which can't be confused for a valid font
family neither but can be passed to wxFont ctor or SetFamily() without
problems.
To ensure that this behaviour is correctly implemented by all ports, rename
the existing wxFont::GetFamily() to DoGetFamily() and call the new method from
wxFontBase::GetFamily() which adjusts the return value if needed.
Closes#12330.

Most of them were dummy and didn't do anything and this API was never meant to
be used anyhow.
Keep just the declarations in wxFontBase but mark them as deprecated.
