Under some circumstances using task isolation can cause deadlocks.
Previously, our task pool implementation would run all tasks in an
isolated region. Now using task isolation is optional and can be
turned on/off for individual task pools.
Task pools that spawn new tasks recursively should never enable
task isolation. There is a new check that finds these cases at runtime.
Right now this check is disabled, so that this commit is a pure refactor.
It will be enabled in an upcoming commit.
This fixes T88598.

Simplify vertex normal calculation by moving the main normal
accumulation function to operate on vertices instead of faces.
Using faces had the down side that it needed to zero, accumulate and
normalize the vertex normals in 3 separate passes, accumulating also
needed a spin-lock for thread since the face would write it's normal
to all of it's vertices which could be shared with other faces.
Now a single loop over vertices is performed without locking.
This gives 5-6% speedup calculating all normals.
This also simplifies partial updates, fixing a problem where
all connected faces were being read from when calculating normals.
While this could have been resolved separately,
it's simpler to operate on vertices directly.
Move BMesh conversion and all loading code into worker.

Added a new api function to stich multires grids
on specific faces in a mesh,
subdiv_ccg_average_faces_boundaries_and_corners,
and changed multires normal calc to use it.
VTune profiling showed that this was a major
performance hit once you get above 10,000 or so
base mesh faces and/or have a high number of
subdivision levels.
Here's a video comparing the difference. Note the
bpy.app_debug switch is not in the final commit.

Also use Curve as an argument instead of Object, since the object was
only used to retrieve the curve, and the calling code is already working
with curve data.
Some of the comments referenced code that was no longer there, or even
defines that were removed. Other comments were more confusing and
vague than helpful. Also adjust formatting in a few cases.
This patch improves the positioning of the little mnemonic underlines
shown under some hotkey letters in menus, especially when using custom
fonts.

No functional changes as logic elsewhere already ensured this.
This just makes it obvious to anyone reading over the code that
these arguments are keyword only.
FOV was expanded to cover the shifting range,
rather than to precisely cut at the image border. Now fixed.

This field was used for extend feature to get handle position of
metastrip children. Since D9972 extend feature works only on meta
strip itself, not it's children.
So `SEQ_transform_get_left_handle_frame()` second argument is always
false and can be removed.
Another instance of `seq->tmp usage` is hack to distinguish strips to be
shuffled, which is not covered by this patch.

Use bounding box tests quickly tell that two components cannot
have a containment relation between each other. This change
cut about 0.6s off a test with 25 big icospheres.
Add a call to orthogonalize the matrix before processing for the
same reasons as D8915, and an early exit in case no limits are
enabled for a bit of extra efficiency.
Since the constraint goes through Euler decomposition, it would
in fact remove shear even before this change, but the resulting
rotation won't make much sense.
This change allows using the constraint without any enabled limits
purely for the purpose of efficiently removing shear.

Since Limit Rotation is based on Euler decomposition, it should allow
specifying the order to use for the same reasons as Copy Rotation does,
namely, if the bone uses Quaternion rotation for its animation channels,
there is no way to choose the order for the constraint.
