GPencil: Refactor: Fix multiedit having less predecence than onion skin

GPencil: Refactor: Move batch cache functions to DRW module

This is in preparation of drawing the overlays.

GPencil: Refactor: Edit Mode: Add support for minor features

Add support for stroke color, vertex opacity and show stroke endpoints.

GPencil: Refactor: Fix old implementation crashing on startup

GPencil: Refactor: Use drawcall matrices instead of custom one

GPencil: Refactor: Add outline overlay

This does not work correctly on square & dot strokes.

Also another issue is the depth blending. We need to fix the depth of
the outline geometry to match the 2D projection we do in the gpencil engine.

GPencil: Refactor: Edit Mode support.

GPencil: Refactor: Replace Stroke Miter break by rounded corners

Also fix stroke ends being twice too long.

GPencil: Refactor: Disable GPencil Outline in edit mode

GPencil: Refactor: Move vertex shader logic to gpencil_common_lib.glsl

This is to be able to reuse the code in other engines/shaders.

GPencil: Refactor: Move iterator to BKE

Cleanup: GPencil: Move GP_MATERIAL_BUFFER_LEN define to a common place
