Replicate the Overlay-Legacy behavior for selected face overlays in
X-Ray mode:
Use depth testing for `edit_mesh_faces_ps_` when X-Ray is fully opaque.
X-Ray is always considered fully opaque in Preview/Render mode since
X-Ray transparency is not supported.

The general idea is to keep the 'old', C-style MEM_callocN signature, and slowly
replace most of its usages with the new, C++-style type-safer template version.
* `MEM_cnew<T>` allocation version is renamed to `MEM_callocN<T>`.
* `MEM_cnew_array<T>` allocation version is renamed to `MEM_calloc_arrayN<T>`.
* `MEM_cnew<T>` duplicate version is renamed to `MEM_dupallocN<T>`.
Similar templates type-safe version of `MEM_mallocN` will be added soon
as well.
Following discussions in !134452.
NOTE: For now static type checking in `MEM_callocN` and related are slightly
different for Windows MSVC. This compiler seems to consider structs using the
`DNA_DEFINE_CXX_METHODS` macro as non-trivial (likely because their default
copy constructors are deleted). So using checks on trivially
constructible/destructible instead on this compiler/system.

Setting the offset to 0 for these cases fixes the issue.
We still want to draw the edit face in this case to a be able
to zoom on the retopo surface. We just don't want the offset.

The detection of when the wireframe is drawn by the edit mode overlays
instead was incorrect and didn't handle recent changes to avoid drawing
edit mode overlay data for invalid evaluated/original edit mesh mappings.
See code comments for more detail.

`OpenSubdiv_Buffer` is a wrapper that was introduced at the time
that Blender couldn't use CPP directly. It contains a pointer to
a VertBuf and callbacks to use GPU module on that buffer.
This PR replaces OpenSubdiv_Buffer with `blender::gpu::VertBuf` and
removes the wrapper.
NOTE: OpenSubdiv tests are added to blender_test executable to make the
library dependencies not to complicated.

This was caused by the normals not being available (default to
`vec3(0)`) which produced `NaN`s down the line after the
unsafe normalize. Changing to `safe_normalize` fixes the issue.
- Avoid redundant computaiton of curve type index masks
- Parallelize index buffer build (always add space for a cyclic segment)
- Avoid overhead of GPU index buffer "add vert" utilities
- Add utility for consistent order of point and handle data
- Make some variable names more consistent
- Avoid mixing multiple abstraction levels in the same function
This wrap some functions as class methods
and rename members to reduce confusion with
the old class meaning.
Rename the old DRWManager to DRWContext.
Also wrap access to DST inside a function
to allow to change it to thread local in a
following PR.
