Add RTF support to wxTextCtrl under macOS

Browse Source 
Add function for setting and getting text control contents as RTF.

For now this is only supported by wxOSX, but support for other platforms
may be added in the future, so wxHAS_TEXTCTRL_RTF or IsRTFSupported()
should be used to test (at compile- or run-time, respectively) whether
RTF support is available.

Closes #24626.
