[subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag.
When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2.
This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.

[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.
