This PR adds a new CC1 option and a new dxc driver option. The DXC
option, when set, is translated into the new CC1 option.
The `all-resources-bound` dxc option will create a metadata module flag,
and the print-dx-shader-flags pass will set the appropriate shader
module flag from this metadata module flag.
