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.

In preparation of TBB we need to split the finalize function into reduce
and free. Reduce is used to combine results and free for freeing any
allocated memory.
The reduce function is called to join user data chunk into another, to reduce the
result to the original userdata_chunk memory. These functions should have no side
effects so that they can be run on any thread.
The free functions should free data created during execution (TaskParallelRangeFunc).

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.
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.

With this change baking jobs will be aborted faster. The user will not have to wait for the current frame to finish baking. The bake job will exit early and discard the incomplete frame.
The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.
This is in preparation of new object types. This only changes mesh_eval, we
may do the same for mesh_deform_eval and other areas in the future if there is
a need for it.
This previously caused a bug in T74283, that should be fixed now.

The cause is not immediately obvious so better to revert and look at this
carefully.

The current "Select Linked" operator works based on mouse position and
makes no sense to call from the menus and was removed in rBdd9dfadaac9b.
This patch adds an operator independent from mouse position that just
selects all keys to a corresponding point (and adds back menu entries,
adds keymap entry).
The original operator is renamed to 'select_linked_pick' internally
(this is now more in line to how "Select Linked" works for meshes,
curves etc)

Selection and grooming only ever happens on hair keys (vertices), so
makes sense to use that theme color.
Sidenote: `CacheEditrPathsIterData` and `PTCacheEdit` have `sel_col` and
`nosel_col`, these can go, will do in a separate commit.

Fluid guiding functionality was broken in the bake / read cache loop in fluid.c. Committing this to the release branch as otherwise fluid guiding would not have worked as expected (i.e. not at all).
The baking progress bar now uses the entire notification space in the UI. Before, old reports could still be visible when a bake job got started. This had the disadvantage that those message got frozen too with the bake UI freeze.
This commit cleans up the flow emission code (i.e. the code that determines where flow is generated). It also addresses an issue with initial velocities.
Related issues (that might be fixed through this commit) are: T73422, T72949
Caused by own rBe02ecd599bdc.
Can happen with e.g. cloth.

Not freeing PTCacheEdit and tagging batch cache dirty on undo will have
a couple of consequences. This patch fixes:
- crash deleting a particle, then undo
- basically any edit (combing, ...), then undo will leave child hairs
untouched
- adding hairs (through mirror, add tool, ...), then undo will leave
'orphaned' child hairs

Fixed sized strings are always initialized & this is not done
elsewhere before calling BLI_path_join.
Remove since it's not needed and makes it read as if the function
might not initialize the output argument.
A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.

Similarly to physics_fluid.c (in same directory) which handled the baking process for Elbeem, there is now physics_manta.c which handles it for Mantaflow.
There are two types of jobs: one for baking and another for freeing. The generic jobs will be used to bake / free specific parts of the simulation (e.g. bake mesh, free particles, etc.).
The jobs are only being used in the "modular" cache mode where the simulation has to be baked in parts.
