[DXIL] Define and generate DXILAttribute and DXILProperty (#117072)
- Redefines `DXILAttribute` to denote a function attribute, compatible
to how it was define in DXC/LLVM 3.7
- Fix how `DXILAttribute` is emitted to be a struct of set attributes
instead of an "or" of the enums
- Implement the lowering of `DXILAttribute` to LLVM function attributes
in `DXILOpBuilder.cpp`. A custom mapping is defined.
- Audit all current ops to specify the correct attributes consistent
with DXC. This is done here to allow for testing.
- Update testcases in `llvm/test/CodeGen/DirectX` of all ops with
attributes to match that attributes are set
- Update testcases of ops that had previously incorrectly set attributes
to check there is no attributes set
- Defines `DXILProperty` to denote the other type of attributes from DXC
used to query properties.
- Emit `DXILProperty` as a struct of set attributes.
- Updates `DXIL.td` to specify applicable `DXILProperty`s on ops

Note: `DXILProperty` was referred to as 'queryable attributes' in design
discussion. Changed to property to allow for better expression in
`DXIL.td`
