GPencil: Add "Self Overlap" parameter to materials to disable Stencil

This parameter was removed in 2.80 and we decided to back again, but now is inverted.

This is to solve the fixed limit defined before.

Also some cleanup and renames.

The function exit before the END_ITER

The edges on the seam should also be allowed to collapse.

Preparations to allow enabling OpenXR API validation layer

For this to work two environment variables have to be set:
XR_API_LAYER_PATH and LD_LIBRARY_PATH, both have to point to the API
layers built by the OpenXR SDK. It also requires you compile Blender
linked to your own SDK build (OPENXR_USE_BUNDLED_SRC disabled).
Further changes will make this set up unnecessary, so validation layers
can be enabled via some flag.

GPencil: Undo clang reformat lines and keep old format

These lines were changed by clang and don't need to be changed.

pass object into object transforms node
