Fix cmap4 overflow pathway.
cmap4 serialize was doing a pop_discard() on overflow, however the encoding record above it was also doing one as well. Remove the unnessecary cmap4 pop_dicard(). Note: in cmap4 there was a comment implying the subsequent pop_discard() would be a noop due to the set error, however is not true since pop_discard() still works when there's been an overflow error.

[subset] consider variation selectors subsetting cmap14
cmap14 subsetting code was not considering variation selectors in the input unicode set when deciding which variant glyphs to keep. This updates subsetting to only keeps variant glyphs if their variation selector code point is in the input unicodes set.

The current CMAP4 implementation uses whatever the current codepoint ranges are and then encodes them as indivudal glyph ids or as a delta if possible. However, it's often possible to save bytes by splitting up existing ranges and encoding parts of them using deltas where the cost of splitting the range is less than encoding each glyph individual.

collect_unicodes() with clamp, calling add_range()
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.
Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.
