b74a7ecc93 Fix IUP differences accoss platforms. 
- Slightly increase the tolerance to account for differences in floating point math across platforms.
- The specific issue is a fused multiply add (d = d1 + (x - x1) * scale; in hb-subset-instancer-iup.cc)
- Also fix more implicit double conversion warnings.

2cfa55056c [instancer] Switch to doubles for delta calculations. 
FontTools uses double's internally so match FontTool's precision so we get the same results more often for floating point calculations.

7145607149 [subset] place the gdef var store at the end of the GDEF table.

975bd39b15 [subset] Match hb rounding to fonttools for avg char width. 
Update Muli and Roboto input test fonts to recalc class values. FontTools recalcs class values during instancing while harfbuzz does not (like the ft subsetter).

ec46c4c2e6 [subset] Update subset test suite to match some changes made to fonttools. 
FontTools has added pruning functionality for code pages which we don't yet have in harfbuzz. Update our test runner to disable that for now. Also match fonttools and always recalc usFirst/LastCharIndex even if no prune unicode ranges is set.

9701b0024e [subset] Always place CFF1/2 char strings at the end of the packed table.

Garret Rieger
c6884377ec [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 3ae2fe2084 rebased onto head w/ tests added.

bbd53fcfa4 Remove glyph_map test that uses retain gids. 
We no longer allow the use of glyph map + retain gids (see: https://github.com/harfbuzz/harfbuzz/blob/main/src/hb-subset-plan.cc#L817). Also add the test to the meson file so it will be run by default.
