Cleanup: simplify uv packing api

Part of a wider set of changes to migrate UV packing from
uv_parametrizer.cc to uvedit_islands.cc.

This allows UV packing improvements including margin calculation,
correctness fixes such as support for non-manifold geometry,
and new packing algorithms including speed and quality improvements.

See for example c2256bf7f714, T82637

This change migrates UV.unwrap and Live UV Unwrap.
