OpenSubdiv: Refactor, move edge map to base folder

OpenSubdiv: Refactor creation of topology refiner

Consolidate it inside of the topology refiner implementation class,
which would allow to store extra data acquired during construction
of the OpenSubdiv's object.

OpenSubdiv: Refactor, use C++ allocation for internal classes

Only use OBJECT_GUARDED_{NEW. DELETE} for structures which are part of
public C-API (and hence can not have new/delete operators overloaded).

Could try being brave and override new/delete from under C++ ifdef.

OpenSubdiv: Refactor, move topology refiner factory to topology folder

OpenSubdiv: Refactor, move topology refiner to own folder

In the future factory will also be moved there.

OpenSubdiv: Refactor, move device specific code to own files

Also, move all device files to own folder.

Makes it so checks for device availability are done in a localized
place.

UI: Skip unnecessary cursor setting

Currently, in sculpting, weight paint and vertex paint modes every cursor
movement triggers redraw of a brush. During that redraw, native cursor is set.
Under the hood, setting the cursor causes freeing of previous cursor and
allocating a new one. In most cases, in previously mentioned modes, recreating
cursor is unnecessary since cursor stays the same.

This patch adds a check which skips cursor change if requested cursor is
already set. The check could be added in pain_cursor.c, but I felt adding it
inside WM_cursor_set function would hopefully skip more unnecessary cursor
reallocations.

Fix T77105: Crashes when clicking "new scene" button

This was introduced on ecc395e473d.

Effectively this is reverting that commit for cases when
scene->toolsettings->sculpt is NULL. But since the facesets are only
working for sculpting this should be fine.

Cycles: Upgraded Embree to version 3.10.0

Cleanup: remove unused Main struct from snap context

Gizmo: lazy initialize snap context

ED_gizmotypes_snap_3d_context_get could have returned NULL,
rename _get(..) to _ensure(..) and initialize the snap context
in this function.

Ruler: Implement Snap Gizmo

The snap point can now be viewed when activating the tool.

Gizmo Library: New Snap Gizmo

Generic snap gizmo to be used for different tools.

The Gizmo can be configured initially by the following properties:
- `"snap_elements_force"`, `"prev_point"`

The following properties can be read as return:
- `"location"`, `"normal"`, `"snap_elem_index"`

This property can be linked to another (tool_setting.snap_elements):
- `"snap_elements"`

And this 3 extra utilities have been added:
- `ED_gizmotypes_snap_3d_draw_util`,
- `ED_gizmotypes_snap_3d_context_get`,
- `ED_gizmotypes_snap_3d_update`.
