Hans Goudey e05c36f56d Fix #113496: PBVH draw crashes and unsupported attribute types
Use more modern approaches for supporting all generic attribute types,
rather than hardcoding all of the types and mistakenly correlating types
and domains.

A "Converter" template class handles conversion to GPU data and
describing the GPU format. The class is based on recent work in Cycles
attribute upload and is meant to replace the `AttributeTypeConverter`
class in `extract_vbo_attributes.cc`. I will do that as a separate step.
This structure will give build errors if new attribute types are added
but not supported here, preventing the situation described in the
report.

All generic attribute types are supported now, consistently with non
sculpt mode drawing. The edge domain isn't supported though.
Typically edges are more costly and complex to access, and interpolation
is less well defined anyway.
