This function calculates two things at once:
1. The total number of vertices emitted by the threadgroup.
2. Exclusive scan of emitted vertex count accross the threadgroup.

For NGG GS, we need to store the following in LDS:
1. The ESGS ring, similarly to legacy ESGS.
2. Emitted vertices from the GS threads.
3. Temporary space used by the workgroup scan.

After each end_primitive and at the end of the shader before emitting
set_vertex_and_primitive_count, we check if the primitive that is being
emitted has enough vertices or not, and we adjust the vertex and
primitive counters accordingly.
As a result, if the backend uses this option, the backend compiler
will not have to worry about discarding the unneeded vertices
and primitives.

Shaders may not use a particular region of a UBO in a given shader (think
UBOs shared between stages, or between shaders), and by just always
extending the existing range for a given UBO, we'd waste bandwidth
uploading it, and also waste our precious const space in storing the
unused data.
Instead, only upload exactly the ranges we can use, and merge ranges when
they're neighbors. We may end up with more upload packets, but the
bandwidth savings is surely going to be worth it (and if find we want a
distance threshold for merging with nearby uploads, that would be easy to
add).
