subset: support subsetting COLRv1 base glyphs 
In COLR.closure_glyphs augment the subset with the glyphs rechable from the COLRv1 base glyphs already in the subset.
In COLR.subset_glyphs, subset and rebuild LayerV1List and BaseGlyphV1List with the base glyphs to keep. Drop COLR if emptied

move PaintFormat enum outside of Paint class nested scope 
When a TTFont is loaded with lazy=True, the otTables are only loaded upon BaseTable.__getattr__
when the requested attribute is not found in the instance __dict__.
Since the Paint.Format enum was defined at class level, every Paint instance, even when loaded
lazily, will have a 'Format' attribute and the magic decompile-on-missing-attribute will not
trigger, since the class attribute will be returned when the instance is missing one.

For this reason, and to not add further special cases, it's better to simply move this Paint.Format
enum class outside to the module level scope, and rename it PaintFormat.

COLRv1: add functions to un-build COLR otTables to raw dicts 
This adds an unbuildColrV1 which does the inverse of colorLib.builder.buildColrV1.
Takes a LayerV1List and BaseGlypV1List and returns a map of base glyphs to raw data structures (list, dict, float, str, etc.).
Useful not only for debugging purpose, but also for implementing COLRv1 subsetting (where we need to drop whole chunks of paints which may be reused by multiple glyphs).

fontBuilder: pass glyphMap to buildCOLR to sort base records by GID 
COLR Base glyph records must be sorted by glyph index. The buildCOLR
function has an optional glyphMap parameter that maps from glyph names
to glyph indices (as returned from TTFont.getReversedGlyphMap()).
FontBuilder knows all that so it should pass it on to colorLib.
