GPencil: Refactor: Stroke Caps: Fix a few issues

- Fix stroke cap flickering
- Fix broken cyclic strokes
- Increase corner split angle from 45� to 60�.

GPencil: Refactor: Implement rounded caps

This was a bit tricky to do it cleanly. We create a mask using the stroke
point coordinates and extend the stroke geometry to uncover the mask if the
round caps are needed.

This was needed to be able to workaround the projection artifact of uvs.

Note that this code could be used for stroke shape in the future.

GPencil: Refactor: Make light power match cycles and EEVEE

This was eyeballed with colormanagement being off. So I wouldn't be
surprise if this comes out not perfect.

GPencil: Refactor: Use more correct depth merge approximation for 2D object

We now use a plane that follows the computed shading normal.
The plane follows the camera rotation but also takes the gpobject volume
into account.

GPencil: Refactor: Use normal approximation for lighting

We compute the normal using the bounding box size and the view vector to
the center of the bounding box. We then scale the normal w.r.t. the BBox
size and transform it back to world space. This gives us a flat normal
for objects without depth and a rotating normal for object that are
not.

This will also be used for correct depth mixing.

GPencil: Only patch grease pencil objects

GPencil: Patch colors to Linear

All colors have been patched to Linear and also changed to PROP_COLOR instead of PROP_COLOR_GAMMA.

The colors have been patched in VFXs and Modifiers.

GPencil: Remove use_solo_mode from Top Layer Popover
