Add setIndexBufferWithFormat method

First step of a multi-part change to bring the setIndexBuffer
method up-to-date with the current WebGPU spec. This change
preserves the previous setIndexBuffer semantics for backwards
compatibility until developers have been notified and given
a grace period to transition to the new signature.
