GPU: Add Polyline shader (wide line emulation)
This new shader is able to emulate smooth wide lines drawing using a
geometry shader.
This shader needs viewportSize and lineWidth uniforms to be set.
There is multiple variants to replace the usage of wide lines for most
shaders.
This patch only fix the gizmo_types files and the navigation gizmo.
Other areas could be fixed afterward, I just limited the patch size.
Fix T57570.
