Primitive Restart implementation
This cl is a very basic implementation of primitive restart
which records every segment of at least 1 primitive into a
vector of index buffers and primitive counts which are then
looped over at draw time. There's no caching involved, so
the primitive restart segments will get recomputed at every
draw, until a caching mechanism is introduced.
Tests: dEQP-VK.pipeline.input_assembly.primitive_restart.*
