Cleanup: use const to for some mask arguments

Cleanup: move mask queries into own file

Similar functions to lookup nearest mask points were in mask_add.c
& mask_edit.c

Cleanup: use 'r_' prefix for output arguments

Also pass some args as 'const'.

Cleanup: update doxy sections

Fix T74662: Prefetching causes random crashes

Caused by 18b693bdbd6b, due to lack of thread safety.
Beteween calling BKE_sequencer_cache_get_num_items and BKE_sequencer_cache_iterate
New items could be inserted in the cache.

BKE_sequencer_cache_iterate() now use 2 callbcack functions for initial setup
during which buffers with correct length can be initialized and finally iterating.

Additionally drawing of unselected items was fixed again introduced in 18b693bdbd6b.

T74662 is reporting quite different symptoms, than I get on my machine, so I am not
entirely sure this is complete fix.

VS2015 has not been supported for a while now but make.bat
still had some support for it.

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.

Overlay: Wireframe: Make facing ratio offset depends on gl_Position.w

This makes the offset dependent of the actual near and far clip distances.

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

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.
