[gvar] Speed up calculate_scalar more
Use a gvar-wide cache of the one active peak index for shared-tuples
that have only one active peak. This speeds up the scalar calculation.
This shows significant speedup for the CJK VarComposite font for
example since that has tens of axes with mostly only one active peak.

[var] Optimize calculate_scalar more
This change alone is showing me 14% scalar in a benchmark.
The reason being that the array::operator[] is not being invoked
a lot of time, which was, many times, hitting the unlikely() path.
Weird!
