Description
Turns out index drawing with render bundles was completely broken due to a simple mistake in render bundle's index checking. The fix is a simple comparision flip, but the fact this wasn't tested is rather concerning! I expanded the vertex_indices test to account for this. The test is already fairly overloaded, but after originally starting a separate testsuite I figured this is after all a great spot for it, also all of the tests there should run anyways with render bundles as well.
In the future we should add more tests that take subsets of vertex & index buffer and test various error cases as well.

Testing
Most of this PR is the test!
(and indeed it breaks without the fix)

This doesn't need backporting as it's not an issue on 0.19, it was introduced in a refactor on main. The cherry-picked test case passes.
