baseVertex in drawIndexed() should be int32, not uint32

baseVertex in drawIndexed() is int32 in web idl. But it is uint32 in Dawn
project. I also checked the native Graphics API sets. baseVertex is int32
on all native APIs (D3D12, Vulkan, Metal). So this feature in web idl is
definitely correct.

This small change makes dawn match web idl for this feature. And it also
adds a couple of tests to cover negative baseVertex.
