[OT] Avoid calling get_glyph() twice
...
Essentially move the glyph mapping to normalization process.
The effect on Devanagari is small (but observable). Should be more
observable in simple text, like ASCII.

[OT] Apply 'rclt' feature in horizontal mode

It's like 'calt', but supposedly always on. We apply 'calt' anyway,
and now apply this too.

[OT] Use general-category, not GDEF class, to decide to zero mark advances
...
At this point, the GDEF glyph synthesis looks pointless. Not that I
have many fonts without GDEF lying around.
As for mark advance zeroing when GPOS not available, that also is being
replaced by proper fallback mark positioning soon.

[GSUB] Wire the font, not just the face, down to substitute()
...
We need the font for glyph lookup during GSUB pauses in Indic shaper.
Could perhaps be avoided, but at this point, we don't mean to support
separate substitute()/position() entry points (anymore), so there is
no point in not providing the font to GSUB.

[GPOS] Adjust mark advance-width zeroing logic
...
If there is no GPOS, zero mark advances.
If there *is* GPOS and the shaper requests so, zero mark advances for
attached marks.
Fixes regression with Tibetan, where the font has GPOS, and marks a
glyph as mark where it shouldn't get zero advance.

Unbreak Hangul jamo composition
...
When we removed the separate Hangul shaper, the specific normalization
preference of Hangul was lost. Fix that. Also, the Thai shaper was
copied from Hangul, so had the fully-composed normalization behavior,
which was unnecessary. So, fix that too.
