Tests: prototype for performance testing framework

Cycles: use OpenCL C 2.0 if available, to improve performance for AMD

Tested with AMD Radeon Pro WX 9100, where it brings performance back to 2.80
level, and combined with recent changes is about 2-15% faster than 2.80 in
our benchmark scenes.

This somehow appears to specifically address the issue where adding more shader
nodes leads to slower runtime. I found no additional speedup by applying this
to change to 2.80 or removing the new shader node code.

Add invert mapping option to proximity weight edit modifier, and some cleanup.

Modifiers: Vertex Weight Edit add invert curve falloff option

This commit adds the option to invert the resulting weights of the
falloff curve.

There is a workflow used by some to convert a texture mask into
vertex weights by using a custom curve and inverting the points.
This allows the same effect with a single click, and gives the modifier
more procedural functionality.

With minor UI tweaks by @mont29.

Cycles: work around OpenCL performance regression after AOVs and vector rotate

We appear to be hitting some limit where adding any amount of code causes a
significant performance regression, no matter what it does. To work around
that a new node level was added.

Cleanup: remove unused Cycles kernel feature flags, replace by node levels

Cleanup: Silence warnings

```
...gpu_texture.c(466,7): warning C4555: result of expression not used
...gpu_texture.c(559,7): warning C4555: result of expression not used
...gpu_texture.c:1205:72: warning: pointer targets in passing argument 4 of ?glGetTexLevelParameteriv? differ in signedness [-Wpointer-sign]
```

Replace VO_DS_EXPAND with SIM_DS_EXPAND

remove unnecessary case in lib_remap.c

rename WITH_SIMULATION_DATA_BLOCK_RNA to WITH_NEW_SIMULATION_TYPE

Cleanup: use switch statement instead of if/else on enum value...

GPencil: Add blank frame when add layer in Dopesheet

When use the dopesheet add layer operator a new blank frame is created. It's very strange to create a layer and don't see anything in dopesheet.

If the layer is added in properties, the frame is not created.

GPU: Estimate a better value for the memory used

This commit adds a `mipmaps` member to the `GPUTexture` struct and also
computes to the memory used by these mipmaps and the memory used for
textures that are created from an external bindcode.

So it solves the following inconsistencies:
- The memory value for mipmaps was not being computed.
- As `GPU_texture_from_bindcode` didn't call
`gpu_texture_memory_footprint_add`, it brought inconsistencies to the
value of the used memory, especially when the texture is freed.

Fix T74782: WorkBench TAA Artifacts During Painting/Drawing

When the TAA is finished the screen can still be redrawn by other
operations without the TAA resets.
If that happened the TAA did add a blank sample to the result as the
scene wasn't drawn, but the was processed.

GPencil: Replace Tint mode "Both" to "Stroke and Fill"

Add new simulation data block

This introduces a new id data block with type `ID_SIM`.

The RNA part of this change is disabled by default for now.
The corresponding cmake option is `WITH_SIMULATION_DATA_BLOCK_RNA`.

The new data block does not yet have an embedded node tree.
I want to add that separately.

This is part of T73324.

The set of files I changed is based on rBb0a1cf2c9ae696.
However, I had to change fewer files, because I did not add a new object type.
