GPencil: Fix more damaged panels

GPencil: Refactor: Fix mask blending

Cleanup: GPencil: Simplify drawing logic.

GPencil: Refactor: Fix mask system not working in some scenes

GPencil: Add missing Vertex Panel

GPencil: More UI fixes after merge

Still more issues pending.

GPencil: First step to fix damaged UI by Brush panel refactor done in master

The patch done in master was done before the Sculpt and Weight brushes were real brushes and also before the Vertex Paint mode was implemented. As result of that, the merge of master has broken almost all panels of brushes and all Vertex Paint mode.

This commit only fix part of the damages.

GPencil: Refactor: Implement Opacity Masking

This is better than previous implementation but has a higher cost.

We render masked layer to a RGBA16F buffer and we then mask the revealage
and the color in a 2 pass blending.

This could maybe optimized a bit to reduce to 1 blending on recent hardware
but the cost will still be way higher than the stencil method.

On the plus side, there is less code change than with the stencil.

Revert "GPencil: Refactor: Add Top to bottom layer masking using stencil"

This reverts commit 6bcd877ebb9a99482bd7f15eae08a3b383b2a706.

This commit has broken all new graese pencil Vertex Paint, Sculpt mode
and Weight mode and need a review.

GPencil: Refactor: Add Top to bottom layer masking using stencil

This uses the 8bits as binary mask layer. This is really
efficient but has the downside of not allowing gradient transparency.

This also allows for different masking ranges and even (maybe) masking
boolean operations (nested masks etc..) but implementing this sort of
this might complexify the UI and the implementation.

The reason we went for binary visibility is that our blending modes
cannot operate correctly if not using a bottom-up rendering of the
layers (due to low precision color buffers). So blending all masked
layers to another temp buffer or blending layer top to bottom is not
doable without loosing the blending features. The workaround for this
would be to use RGBA16F everywhere and use many double buffers. Which
would kill performance and is really unpractical.

Now we just limit the number of masks to be 8. Lifting this limit
is a todo.
