Support loops at the GLSL level instead of relying on
NOD_shader_nodes_inline.
This improves compilation and runtime performance, avoids causing
recompilations on iteration count changes, and allows supporting
dynamic iteration counts.

This allows to reduce the number of includes for each
tree graph (surface, volume, displacement) and
reduce the code size significantly for most vertex
shaders, speeding up compile time.

This makes it possible to restore previous Blender 4.3 behavior of bump
mapping, where the large filter width was sometimes (ab)used to get a bevel
like effect on stepwise textures.
For bump from the displacement socket, filter width remains fixed at 0.1.
