[HLSL][DXIL] Implement refract intrinsic (#147342)

- [x] Implement refract using HLSL source in hlsl_intrinsics.h
- [x] Implement the refract SPIR-V target built-in in
clang/include/clang/Basic/BuiltinsSPIRV.td
- [x] Add sema checks for refract to CheckSPIRVBuiltinFunctionCall in
clang/lib/Sema/SemaSPIRV.cpp
- [x] Add codegen for spv refract to EmitSPIRVBuiltinExpr in
CGBuiltin.cpp
- [x] Add codegen tests to clang/test/CodeGenHLSL/builtins/refract.hlsl
- [x] Add spv codegen test to clang/test/CodeGenSPIRV/Builtins/refract.c
- [x] Add sema tests to clang/test/SemaHLSL/BuiltIns/refract-errors.hlsl
- [x] Add spv sema tests to
clang/test/SemaSPIRV/BuiltIns/refract-errors.c
- [x] Create the int_spv_refract intrinsic in IntrinsicsSPIRV.td
- [x] In SPIRVInstructionSelector.cpp create the refract lowering and
map it to int_spv_refract in SPIRVInstructionSelector::selectIntrinsic.
- [x] Create SPIR-V backend test case in
llvm/test/CodeGen/SPIRV/hlsl-intrinsics/refract.ll
- [x] Check for what OpenCL support is needed.

/// \fn T refract(T I, T N, T eta)
/// \brief Returns a refraction using an entering ray, \a I, a surface
/// normal, \a N and refraction index \a eta
/// \param I The entering ray.
/// \param N The surface normal.
/// \param eta The refraction index.
///
/// The return value is a floating-point vector that represents the refraction
/// using the refraction index, \a eta, for the direction of the entering ray,
/// \a I, off a surface with the normal \a N.
///
/// This function calculates the refraction vector using the following formulas:
/// k = 1.0 - eta * eta * (1.0 - dot(N, I) * dot(N, I))
/// if k < 0.0 the result is 0.0
/// otherwise, the result is eta * I - (eta * dot(N, I) + sqrt(k)) * N
///
/// I and N must already be normalized in order to achieve the desired result.
///
/// I and N must be a scalar or vector whose component type is
/// floating-point.
///
/// eta must be a 16-bit or 32-bit floating-point scalar.
///
/// Result type, the type of I, and the type of N must all be the same type.
