draw: add fetch-shade-emit path

Enable with TEST_FSE=t.  Performs fetch from API-provided vertex buffers,
transformation with one of three (two working) hard-coded shaders, and
final emit to hardware vertices all in a single pass.

Currently only really useful for profiling in conjunction with SP_NO_RAST=t.
