All of the draw variants except drawIndexed support all base arguments
as part of the draw call that is recorded. Updated drawIndexed to use
the "instance" version and draw 1 instance if the baseVertex is not 0.
Previously, if we bound the buffer at a non-zero offset, but then
passed in 0 for the base vertex/instance relative to that, it would
reset the vertex offset to 0. This also cuts down on the number of
commands recorded since draws will only correspond to one command.
