[Ligature] Speed up
Match the first component of the ligature in the LigatureSet loop.
Speeds up Roboto shaping by 25%. I don't think it breaks anything.

[GPOS] Fix assert fail introduced recently
Was introduced in 8708b9e081192786c027bb7f5f23d76dbe5c19e8.
If these lookups are recursed to from (Chain)Context out-of-order,
it was possible that last_base > buffer->idx, in which case we
were attaching marks to a base after them... and an assertion
was failing fortunately.

While on a fuzzer-found test case (added) that loop was faster,
on real fonts, including NotoNastaliq in our benchmark, it was
actually slower, which intuitively I would have expected.
