[HLSL][DXIL][SPRIV] Added WaveActiveMin intrinsic (#164385)

Adds the WaveActiveMin intrinsic from #99169. I think I did all of the
required things on the checklist:
- [x]  Implement `WaveActiveMin` clang builtin,
- [x]  Link `WaveActiveMin` clang builtin with `hlsl_intrinsics.h`
- [x] Add sema checks for `WaveActiveMin` to
`CheckHLSLBuiltinFunctionCall` in `SemaChecking.cpp`
- [x] Add codegen for `WaveActiveMin` to `EmitHLSLBuiltinExpr` in
`CGBuiltin.cpp`
- [x] Add codegen tests to
`clang/test/CodeGenHLSL/builtins/WaveActiveMin.hlsl`
- [x] Add sema tests to
`clang/test/SemaHLSL/BuiltIns/WaveActiveMin-errors.hlsl`
- [x] Create the `int_dx_WaveActiveMin` intrinsic in
`IntrinsicsDirectX.td`
- [x] Create the `DXILOpMapping` of `int_dx_WaveActiveMin` to `119` in
`DXIL.td`
- [x] Create the `WaveActiveMin.ll` and `WaveActiveMin_errors.ll` tests
in `llvm/test/CodeGen/DirectX/`
- [x] Create the `int_spv_WaveActiveMin` intrinsic in
`IntrinsicsSPIRV.td`
- [x] In SPIRVInstructionSelector.cpp create the `WaveActiveMin`
lowering and map it to `int_spv_WaveActiveMin` in
`SPIRVInstructionSelector::selectIntrinsic`.
- [x] Create SPIR-V backend test case in
`llvm/test/CodeGen/SPIRV/hlsl-intrinsics/WaveActiveMin.ll

But as some of the code has changed and was moved around (E.G.
`CGBuiltin.cpp` -> `CGHLSLBuiltins.cpp`) I mostly followed how
`WaveActiveMax()` is implemented.

I have not been able to run the tests myself as I am unsure which
project runs the correct test. Any guidance on how I can test myself
would be helpful.

Also added some tests to the offload-test-suite
