DXC: assert if a flag is unhandled

This avoids issues such as the one I recently fixed, where we were
setting D3DCOMPILE_SKIP_OPTIMIZATION, but this wasn't being handled in
the backend.

Also, since DXC's default opt level is /O3, but we are using the FXC
macros, where the default is /O1, make sure to explicitly set /O3 when
using DXC. This ensures that we _can_ use /O1 in the future by setting
D3DCOMPILE_OPTIMIZATION_LEVEL1.
