Detected when testing mr_elephant on an Intel HD520. When copying
the velocity buffer using the copy shader, the number of scheduled
workgroups could be larger than supported by the device.

This PR fixes this by copying multiple vertices per thread when
the work size cannot cover all the pixels.

74b128dd6d EEVEE-Next: Fix motion blur large geom on low end devices 
Detected when testing mr_elephant on an Intel HD520. When copying
the velocity buffer using the copy shader, the number of scheduled
workgroups could be larger than supported by the device.

This PR fixes this by splitting the copy pass in multiple smaller
passes so the velocity is copied.

NOTE: I didn't went for the approach to add a new workgroup dimension
as that would lead to more overhead when using more smaller meshes. I
would assume these devices would more often be used with scenes with
smaller geometry.

I also tried

int vertices_per_call = VERTEX_COPY_GROUP_SIZE * GPU_max_work_group_count(0);
      for (int sub_offset = geom.ofs, sub_len_left = geom.len; sub_len_left > 0;
           sub_offset += vertices_per_call, sub_len_left -= vertices_per_call)
      {

but didn't like the readability.

I would rather have the for loop inside the shader. This will reduce the amount of command send.

Do not use this header. Use gpu_shader_math_base_lib.glsl instead. common_math_lib is legacy.

Don't use that only for the group size. Use gl_WorkGroupSize instead.
