[glyf] Don't accept gids higher than maxp's glyphs number
...
This specially becomes concerning on sub-components where a gvar table
that is sanitized using maxp's glyphs number overflows when a high gid
accepted here goes to it, maybe an additional check can be put there
also, this however feels to be enough.

They aren't contributing to rendering and making issue for stroking, let's skip them
ourselves as Skia does also https://skia-review.googlesource.com/c/skia/+/268166
They are useful for extracting extents and so which that functionality won't be effected by this change.

Specially checks correctness of the API semantics:

* no path will be left open and close-path will happen at the end of opened paths.
* no path opens with a move-to and will be closed with no length.
* paths start and ending points matches.
* no line/quadratic/cubic command will be issued when no path is started.
