[DirectX] Implement UseNativeLowPrecision shader flag analysis (#134288)
Fixes #112267
Implement the shader flag analysis to set the UseNativeLowPrecision DXIL
module flag.
The flag is only able to be set when the command-line flag
`-enable-16bit-types` is passed to clang-dxc, or equivalently
`-fnative-half-type` is passed to clang.
When the command-line flag is passed, a module metadata flag called
"dx.nativelowprec" is set to 1.
The DXILShaderFlags shader flags analysis checks that the module
metadata flag "dx.nativelowprec" is set to 1 and the DXIL Version is 1.2
or greater before setting the UseNativeLowPrecision DXIL module flag.
