[DXContainer] Update DXContainer to match D3D12 spec (#143201)

Update the descriptor range flag values in DXContainerConstants.def to
match
the Direct3D12 specification. This changes two aspects:

1. Modify the DESCRIPTOR_RANGE_FLAG macro to use direct values instead
of
   bit shifts
2. Update the flag values to use hex notation and match D3D12's
   D3D12_DESCRIPTOR_RANGE_FLAGS enumeration:
   - DESCRIPTORS_VOLATILE: 0x1
   - DATA_VOLATILE: 0x2
   - DATA_STATIC_WHILE_SET_AT_EXECUTE: 0x4
   - DATA_STATIC: 0x8
   - DESCRIPTORS_STATIC_KEEPING_BUFFER_BOUNDS_CHECKS: 0x10000
3. Removed NONE value from ROOT_DESCRIPTOR_FLAG

This ensures better compatibility with the D3D12 API and makes the
values
more explicit in the code.
