Jeroen Bakker dbd57153be GPU: Patch GPencil shader for metal support. 
The stoke shader of grease pencil uses a geometry shader stage. Apple
devices don't support shaders with geometry shader stage. In the
OpenGL driver there was a pass-through implemented so it didn't fail.

When using the metal backend this needs to be solved more explicitly.
This change patches the grease pencil shader to support both the
backends supporting a geometry stage and those without.

Fixes #105059
