T75631: New multires shrinkage problem

The old Subdivide button was behaving as if subdivision modifier was
applied on top of the multires. This was the source of shrinkage since
the behavior of the limit surface: limit surface of a sparse point
from another limit surface makes final result appear smaller.

The new behavior is based on propagating delta against base mesh's
limit surface to the top level. Effectively, this is as if we've
sculpted on old top level and then propagated to the new top level.

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.
