GPUShader: GL backend isolation

Cleanup: GPU: Replace Batch uniform by shader uniform using macro

This is a first step into removing uniforms from GPU_batch and Imm.

UI: Fix protential stray GPU state preventing correct drawing

Fix potential issue with nodetree introduced in rB47c6f41b8926.

BLI_kdopbvh: Adjust epsilon according to the axis

This corrects the overlap detection for cloths since in this case kdop26
is used and epsilon represents the distance.

Depsgraph: simplify DEG_evaluate_* API

This mainly removes the bmain argument, which can be
retrieved from the graph itself.

Also, I removed some outdated/unnecessary comments.

Sculpt: Enable Cloth Simulation Target for Pose and Boundary

This adds a new brush property called "Deformation Target" which
controls how the brush deformations is going to affect the mesh data. By
default is set to Geometry, which makes the brushes displace the
vertices. When set to Cloth Simulation, the deformation of the brush is
applied to the cloth solver constraints, so the simulation is
responsible to apply the final deformation. This allows to add cloth
simulation effects to other sculpt tools with minor modifications to their
code.

This patch enables Cloth Simulation deformation target for Pose and
Boundary brushes, which are tools that are already designed to work in
low poly counts and produce large deformations. This allows creating the
most common cloth effects, like bending and compressing folds, without
relying on collisions.

Sculpt: Erase Displacement Mesh Filter

Same concept as the Multires Displacement Eraser Brush but implemented
as a mesh Filter. This allows to delete the displacement of an entire
area uniformly.

Cleanup: Node: Use checker shader for preview background

Removes many drawcalls which might have slowdown the UI.

Sculpt: Invert Smooth to Enhance Details

This enables the invert mode in the smooth brush as Enhance Details.
The operation is similar to the Sharpen Filter intensify details parameter,
which consist in applying the laplacian smooth displacement in the opposite
direction calculated using the original coordinates.

Fix compiler error in MSVSC

It broke building on windows, initializing a static may not be done with a function in C.

Fix T79714: Projecting texture from camera fails

The evaluated mesh is now only recomputed when the required data layers
are missing. Previously the evaluated mesh was re-evaluated incorrectly,
which caused the stippled result and the failing assert.

Since now only the evaluated mesh is used, and never a temporary mesh,
there is also no more need to keep track of whether the mesh needs
freeing or not.

Fix T77564: VSE (and compositor background) lost stereoscopy preview

Issue introduced on fe045b2b77dc6d7f0b552619fe824b496d34db6c.

Since the stereoscopy compositing (anaglyph, ...) is only done for
viewports the VSE preview and compositor need to use viewports.
