This PR revises the descriptions of DXIL module flags. Descriptions such as `D3D11_1_SB_GLOBAL_FLAG_SKIP_OPTIMIZATION` are referring to Global Flags in DXBC. DXBC is not a supported backend target, so references to DXBC should not be present. There is also confusion with regards to the description of the `LowPrecisionPresent` DXIL module flag, which currently reads `D3D11_1_SB_GLOBAL_FLAG_ENABLE_MINIMUM_PRECISION` and implies the use of minimum-precision to handle 16-bit types. However this is not true, because both the flags `LowPrecisionPresent` and `UseNativeLowPrecision` can simultaneously be set in the same DXIL module, and minimum precision mode is mutually exclusive with native low precision. This PR revises the description of the `LowPrecisionPresent` flag to accurately describe what it represents.
