This requires some changes in the wire because WireCmd doesn't know the
size of void. This also adds a handwritten implementation of the Wire
commands for SetSubData that internally converts to uint8_t so that
WireCmd can generate the de/serialization.

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.

This splits off part of CommandBufferBuilder in separate

These encoders are pure frontend objects and record into the
CommandBufferBuilder command allocator objects, so no changes to the
backends were needed.
Error handling is still ew, because the "builder" mechanism we had
