Vadim Zeitlin a349dc1085 Handle underlined and strikethrough attributes in wxGTK native font info.
These attributes were not handled by wxFont::GetNativeFontInfoDesc() as it
only serialized the Pango font description which doesn't support them.

Fix this by handling these attributes explicitly and prepending them to the
Pango font string if necessary.

Closes #14559.
