Fix T64903: Freestyle line alpha not working for Eevee

GPU: double uniform names buffer size

Adding a constant yields quadratic time complexity which can
have quite a big impact on some scenes.

I used the file from T64901 for testing.
In the test file, the time it took to execute `wm_draw_update`
changed from `0.60s` to `0.51s`.

Particle: optimize threading for many particles and many cores

The maximum particles per task of 256 was outdated and lead to too much thread
contention. Instead define a low fixed number of tasks per thread.

On a i7-7700HQ, creating 4 million particles went down from 31s to 4s.

Thanks to Oscar Abad, Sav Martin, Zebus3d, Sebasti�n Barschkis and Martin Felke
for testing and advice.

Viewport: MSAA support during ViewportRendering

When rendering viewport to an offscreen buffer the buffer was
constructed for non anti aliasing (0 samples). This made the objects
that are drawn by the `object_mode` including `wireframe` draw type
non-anti-aliased.

The offscreen buffers will be constructed based on the user setting for
viewport multisampling (`U.ogl_multisamples`). The same setting will
also be used when previewing scene strips in the sequencer. For now
this only improves wireframe drawing in the scene strips. To improve the
Anti aliasing in the scene strips we need to get finer control in the
draw manager. This will be part of a different patch I am preparing.

Please note that this patch also cleansup some unused code in the offscreen rendering (FSAA code was still existing, but never called)

OffscreenRendering: Fix Incorrect Window Coordinates

When doing offscreen rendering (Viewport Render or Sequencer Scene
strip) EEVEE and workbench used the wrong window coordinates. These
coordinates included the border that was not drawn.

Fix T64842: crash rendering files with bevel curves

This is old logic that no longer makes sense in the new depsgraph, and causes
issues when multiple threads try to modify the same bevel object.

CTest: Fix Bli_task_test failing on windows.

The task_scheduler was not being explicitly freed, leading to
unpredictable behavior when the process was exiting. The test
would pass, but would sometimes segfault at process shutdown.

Cleanup: use term pad instead of padding

- Use min/max instead of bottom/top
(in keeping with the rest of the BLI_rect API).
- Swap args (was passing in max, min).
