[Bf-codereview] Convex hull bmesh operator (issue 6114060)

LGTM,

one more general comment is that I think having the operator delete the
holes its self might not be so good.

Instead the blender operator could do this on faces tagged as original.
- This isnt really bad, just think it can get a bit messy if a lot of
operators call eachother because of functionality users might want.
rather have them low level and the callers can mix together the
operators that make sense in some context. In this case the caller is
the wmOperator
