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.

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.

GPencil: Refactor: Fix crash caused by material preview render

DRW: Add DRW_shgroup_stencil_set to set all stencil test values

This is to allow more fine tuning. The other function is
deprecated and need to be replace.

UI: tweaks to the brush Stroke panel

- Make sure the spacing controls are together
- Add separators around the dash controls

Revert "GPencil: Refactor: Change Mask Behavior"

This reverts commit eb3fe4c8486fe1253cf8725b6083238dca7d256e.

GPencil: Refactor: Change Mask Behavior

This is a work in progress Masking now done by a particular layer and
applied on all layers underneath.

GPencil: Refactor: Fix broken selection

UI: Brush Settings overhaul

This makes a number of changes to the tool settings brush UI:

- All brush-related controls are now grouped together, so you can see which items are brush settings are which are not. Previously it was all jumbled together.
- The brush picker is in a separate panel, so that you can switch brushes without worrying about the settings, or vice versa.
- Custom Icon settings moved from the Display settings(now known as Cursor) to the Brushes panel.
- UnifiedPaintSettings panels are removed and the contained options are now next to their relevant setting with a globe icon toggle. This is not displayed in the header.
- 2D Falloff and Absolute Jitter toggles were changed into enums, to make it clearer what happens when they are on or off.
- Adjust Strength for Spacing option was in the Options panel in some modes, but in the Stroke panel in others. It is now always under Stroke.
- Display (now Cursor) panel was reorganized, settings renamed.
- 2-option enums are annoying as a drop-down menu, so they are now drawn with expand=True.
- Smooth Stroke and Stabilizer options in grease pencil and other paint modes are now both called "Stabilize Stroke", for consistency and clarity.
- De-duplicated some drawing code between various painting modes' brush options. I tried to keep de-duplication reasonable and easy to follow.
- A few more tweaks - see D5928 for the extensive list.

Most of the patch is written by Demeter Dzadik, with some additions by myself

fix wrong comparison

fix some warnings

remove some old tests

remove unused functionality

use new indices functions

more low level generic CPPType functions

Industry Compat keymap: Add support for the context menu PC keyboard key

Industry Compat keymap: Fix issue in UV editor Box Select tool

Shift-dragging with the Box Select tool would also select the nearest point.

Using a Click instead of Press event for selection (just like the default keymap) fixes this.
