[ot-layout] Synthesize missing baselines
...
Add a variation of hb_ot_layout_get_baseline that
synthesizes missing baselines, using heuristics in part
taken from the CSS Inline Layout Module, Level 3.
Includes some new tests for synthesized baselines.
The base2.ttf is a subset of Noto Sans Bengali that
includes just the Bengali Ka.
New API: hb_ot_layout_get_baseline_with_fallback

[draw/test] Swap a freetype test case with a simpler one
...
As CI failure, apparently the my local freetype and CI one have different
result so let's switch the case with a simpler one just to test quadratic command
is emitted correctly.

[draw/glyf] Emit empty contours
...
This makes it actually match freetype behaviour even though rasterizer
should filter such contours specially for stroking.
See https://github.com/harfbuzz/harfbuzz/pull/3411#discussion_r802283827 for the context.

This is unnecessary overhead. Up to rasterizers to handle this. Plus,
