This patch enables TBB as the default task scheduler. TBB stands for Threading Building Blocks and is developed by Intel. The library contains several threading patters. This patch maps blenders BLI_task_* function to their counterpart. After this patch we can add more patterns. A promising one is TBB:graph that can be used for depsgraph, draw manager and compositor.
Performance changes depends on the actual hardware. It was tested on different hardwares from laptops to workstations and we didn't detected any downgrade of the performance.

Basically this new tool constitutes a macro that uses the parameters of
the Extrude and Translate operators that were recently implemented.
Thanks to @CandleComet for initial implementation.

This solution involves adding a uniform to each fragment shader that is
used by gizmo drawing and use the framebuffer state to set this uniform
accordingly.
This solution can also be carried to external shaders (addons).
A single line of code would then be enough to fix the issue.
The only trickery here is the dummy define:
`#define srgb_to_framebuffer_space(a)`
This is in order to avoid breaking other DRW shaders that use the same
fragment shader code but do not need the tranformation.

Starting select linked failed when the selected vertex or edge
was it's self delimiting.
Support using these elements for linked select
as long as they're part of an isolated selection.
When the modal operator passes events, free the internal state of
the operator as we can't be sure those events don't cause the mesh data
to be re-allocated or removed.
Longer term it might be best to make this into a tool since
the main purpose of this operator is to run other actions.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Change to recent renaming of "Edge Collapse" as it has multiple uses,
as it collapses edge-rings, but isn't limited to collapsing single edges,
it can be used to collapse faces with arbitrary topology.
The name "Collapse Regions" is too vague, users might not think to use
this to collapse edge-rings.
Use a more verbose name "Collapse Edges & Faces", referencing edge-rings
in the tool-tip.
This is useful for collapsing regions of faces & edges,
similar to a 'Merge -> Collapse' which can operate on multiple regions,
merging UV's so they don't need to be manually corrected.
The name & description didn't mention this.
The edge split operator can now split faces & edges
from selected vertices.
This has the same functionality as manually ripping all
faces and edges away from a vertex.
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

Mask extract modifies the topology when adding the boundary loop, so
previous face sets may not be correct in the new mesh. Remove the face
sets datalayer and let sculpt mode rebuild it when entering sculpt mode
in the new object.

Was crashing SculptSession data will not longer be valid if the total
number of polys is modified when rendering the mesh again.
This deletes all face sets in the mesh when slicing the mask. I'll try
to add code to generate a new face set in with faces that are created
when filling the holes, but for now this avoids the crash.

While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.
