c8f6ae1df7 [subset/hvar/retaingids] Synthesize a DeltaSetIndexMap if needed 
Before we were emitting the entire VarStore rows if advMap
was Null. Instead, synthesize an advMap.

20% speed up in subset_glyphs/SourceHanSans-VF.otf/retaingids benchmark.

afe0910295 [font] Actually deprecate get_glyph_shape() 
We previously marked it as deprecated in the documentation but didn’t
actually deprecate it in code. Now the only known users have migrated to
draw_glyph(), lets deprecate o=it for good.

Fixes https://oss-fuzz.com/testcase-detail/5979721620652032. Timeout was caused by degenerate map insert behaviour due to poor integer hash function. Presize the map to avoid it. Also fixes collect_mapping() for cmap format 13.
