This is the first step for having a fully operational SPVC usage
path. This version of SPVC integration uses SPVC for setting up the
options to the compiler, but a lot of the actual interaction with
spirv-cross is done in Dawn, just via SPVC's compiler object.
Future CLs will migrate more of the spirv-cross interaction to using
the SPVC API, eventually removing the need for Dawn to know about
spirv-cross.

When both the vert and frag shaders have a UBO binding, the D3D12
backend was using register offset 0 for both, causing a collision,
and the wrong constant value used in one of the shaders.
The fix is to use the binding offsets computed by the BindGroupLayout,
since they know about all of the bindings, not just the ones computed
for each shader. This made it necessary to defer shader compilation
until pipeline layout creation time (as is done in the Metal backend
for similar reasons).
Finally, those bindings offsets computed by the BGL include an offset
for the CBV, UAV and SRV subgroups, so we must add the same register
offset when assigning the BaseShaderRegister to the descriptor ranges
in the PipelineLayout constructor so that they match.

This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.
