[HLSL][DXIL][SPIRV] Implementation of an abstraction for intrinsic selection of HLSL backends (#87171)

Start of #83882
- `Builtins.td` - add the `hlsl` `all` elementwise builtin.
- `CGBuiltin.cpp` - Show a use case for CGHLSLUtils via an `all`
intrinsic codegen.
- `CGHLSLRuntime.cpp` - move `thread_id` to use CGHLSLUtils.
- `CGHLSLRuntime.h` - Create a macro to help pick the right intrinsic
for the backend.
- `hlsl_intrinsics.h` - Add the `all` api.
- `SemaChecking.cpp` - Add `all` builtin type checking
- `IntrinsicsDirectX.td` - Add the `all` `dx` intrinsic
- `IntrinsicsSPIRV.td` - Add the `all` `spv` intrinsic

Work still needed:
- `SPIRVInstructionSelector.cpp` - Add an implementation of `OpAll` for
`spv_all` intrinsic
