Fix Wireframe issue with infront objects

We were testing against the stencil buffer but the actual stencil was not
the one expected. But with current implementation it is not even required
so we just bypass it.

deduplicate node creation

Fix T71924: Baking quaternion keyframes gives discontinuous values

PyAPI: add Quaternion.make_compatible

Fix quaternion compatibility function

Use closest quaternion instead of only checking w sign flipping,
which didn't catch all cases.

Clip Editor: Fix uninitialized plane track grabbing points

Was happening when there was an image assigned to the track.

Another pair programming session with Clement.

Clip Editor: Fix visualization of plane track image

Pair programming with Clement.

Fix infront selectability of solid objects

initialize ids of xnodes

free memory of inlined node tree

Fix In Front object selectability

We use the same trick as before but we now isolate it to a drawmanager
state to avoid loosing track of the state.

Fix T64655: Quad view toggle conflicts on macOS

Cmd-Alt-Q is a system shortcut on macOS, use Ctrl-Alt-Q.

BLI_task: Add pooled threaded index range iterator, Take II.

This code allows to push a set of different operations all based on
iterations over a range of indices, and then process them all at once
over multiple threads.

This commit also adds unit tests for both old un-pooled, and new pooled
task_parallel_range family of functions, as well as some basic
performances tests.

This is mainly interesting for relatively low amount of individual
tasks, as expected.

E.g. performance tests on a 32 threads machine, for a set of 10
different tasks, shows following improvements when using pooled version
instead of ten sequential calls to BLI_task_parallel_range():

| Num Items | Sequential | Pooled | Speed-up |
| --------- | ---------- | ------- | -------- |
| 10K | 365 us | 138 us | 2.5 x |
| 100K | 877 us | 530 us | 1.66 x |
| 1000K | 5521 us | 4625 us | 1.25 x |

Note: Compared to previous commit yesterday, this reworks atomic handling in
parallel iter code, and fixes a dummy double-free bug.

Now we should only use the two critical values for synchronization from
atomic calls results, which is the proper way to do things.

Reading a value after an atomic operation does not guarantee you will
get the latest value in all cases (especially on Windows release builds
it seems).

USD: clarification of USDAbstractWriter::is_supported()

USD: iterate() ? iterate_and_write()
