[subset] Fix for fuzzer timeout.

Fixes https://oss-fuzz.com/testcase-detail/5549945449480192
In prune_langsys: move LangSys visited check up before any work is done for a LangSys. In this particular case the compare() method is responsible for the majority of the time spent and wasn't being guarded with a visisted check.

[ci] Try harder to fix this randomly failing job
...
The default --num-processes is the number of CPUs multiplied by 5,
which seems to give this VM a hard-time. Even the number of CPUs is too
much, so lets use half of that (I’m adding one just in case the division
gives zero).

[repacker] Clear distance and position cache when assigning a new space.

A change in space will effect the distance assigned to the node and any of it's children so clear the distance cache.

[subset] (Chain)ContextSubst glyph_closure fix

- When pos_glyphs is empty, use current full glyphs set as input for
subsequent recursive closure process
- Also increase max_lookup_visit_count to 35000 cause a real font file hit
previous limit 20000 and some lookups are dropped unexpectedly

[repacker] Improve vertex priority packing.
...
Previous priority implementation would move a node further back within it's layer, but at max priority was unable to move any further up than that. This updates the implementation to have 3 priority levels:
1. Distance is reduced by half of table size.
2. Distance is reduced by full table size (move to beginning of the layer).
3. Distance is set to 0. Vertex will be packed as soon as possible.
Also makes the iterative resolutions aware of max priority, so it won't keep trying to raise priority beyond the maximum.
