Re-organize cross-platform support for text input methods.

FLTK 1.3 supports complex text input methods (TIMs) for the 3 platforms
(X11, Windows, macOS). This support has an interface with FLTK that is
common for X11 and Windows, via (undocumented) functions fl_set_spot(),
fl_set_status() and fl_reset_spot().
In contrast, and because it's been developed independently, the
interface between the macOS TIM and FLTK 1.3 is completely different :
static functions FL::insertion_point_location() and Fl::reset_marked_text().

The present change implements a single TIM/FLTK interface
used by all platforms based on functions fl_set_spot() and
fl_reset_spot().

The previous macOS-specific functions FL::insertion_point_location() and
Fl::reset_marked_text() are maintained only for compatibility with 1.3
and deprecated.
