[repacker] fix bug where nodes with incoming virtual links could get orphaned.
When attempting to fix overflows nodes that have incoming edges from more than one parent can be duplicated. However, if all of these incoming links are virtual except for one duplicating it will effectively orphan it (one of the copies will be pointed to only by virtual links). Since parent book keeping is expensive we don't want to separately track virtual/real parents so instead just don't duplicate nodes that have at least one incoming virtual link.

Update classdef size estimator to pick the min coverage format.
Previously this just assumed a worst case format 1.

[repacker] Rework how ClassDef sizes are estimated during splitting.
The old approach considered only one class at a time, which in some cases can generate the wrong answer. This change updates the estimation to consider how all classes in the current split would end up encoded in a single ClassDef table. Additionally compute whether glyphs are consecutive only for the current split (instead of the fully mapping).

[graph] Use a hb_map_t to keep parents, instead of hb_vector_t
In some fonts, for example Noto Duployan-Regular, nodes can
have over a thousand parents... Speeds up 10% subsetting.
