GPencil: Test to move cache to datablock

This move the cache and assign orig pointers to Stroke and Points

GPencil: Fix missing Vertex Top options in texture material

Merge branch 'greasepencil-object' into greasepencil-refactor

Merge branch 'master' into greasepencil-object

GPencil: Refactor: Remove per layer random color jitter in wireframe

This is barely noticeable and makes it more confusing than anything in the
code. It's also faster and follow solid mode more closely.

GPencil: Refactor: Fix gradient behavior in texture color mode

GPencil: Refactor: Make Texture UV transform behave like normal 3D ones

Meaning we apply location then rotation then scale. This makes positioning
using the parameters easier.

Also since the gradients now use the same UV space, we can reuse the same
properties for the transform.

GPencil: Fix vertex color draw tool color blending

This removes the darkened color artifacts due to incorect alpha blending.

GPencil: Refactor: Add fill vertex color suppport

This is a waste of GPU memory tho. It is duplicated for each gp points.

A better approach would be to store a per stroke data that we could fetch
using a stroke id.

GPencil: Rename mix_color to vert_color

Also renamed mix_color_fill to vert_color_fill

GPencil: Refactor: Enable Vertex color mode in vertex paint

This is to follow the same behavior as meshes.

GPencil: Refactor: Fix is_render flag

This should fix VFX toggling for render mode only.

GPencil: Refactor: Support solid mode color modes

This should be a 1:1 feature parity with what the workbench do with meshes
objects.

GPencil: Cleanup more unused code

GPencil: Remove unused variable

GPencil: Refactor: Make Lighting effect only happen in lookdev & render mode

This makes the lighting behavior much more consistent with the other objects.

Cleanup: GPencil: Remove unecessary comment

GPencil: Refactor: Fix depth sorting with workbench render

Cleanup: GPencil: Move shader static variable to gpencil_shader.c

GPencil: Refactor: Fix surface projected stroke not shown during stroke
