imgui_freetype: fixed a packing issue which in some occurrences would prevent large amount of glyphs from being packed correctly. (#5788, #5829)

Browse Source 
This seemingly innocuous change sursingly had very large side-effects of completly breaking packing for the test font mentioned in above issue. Not even sure why tbh. New code matches what stb_truetype's stbtt_PackBegin() does.

- Misc: added GetItemID() in public API. It is not often expected that you would use this,
but it is useful for Shortcut() and upcoming owner-aware input functions which wants to
be implemented with public API.
- Fonts: imgui_freetype: fixed a packing issue which in some occurrences would prevent large
amount of glyphs from being packed correctly. (#5788, #5829)
- Fonts: added a 'void* UserData' field in ImFontAtlas, as a convenience for use by
applications using multiple font atlases.
- Demo: added "Inputs->Shortcut Routing" section.
