Add `environment` parameter to Clang availability attribute. The allowed values for this parameter are a subset of values allowed in the `llvm::Triple` environment component. If the `environment` parameters is present, the declared availability attribute applies only to targets with the same platform and environment. This new parameter will be initially used for annotating HLSL functions for the `shadermodel` platform because in HLSL built-in function availability can depend not just on the shader model version (mapped to `llvm::Triple::OSType`) but also on the target shader stage (mapped to `llvm::Triple::EnvironmentType`). See example in #89802 and microsoft/hlsl-specs#204 for more details. The environment parameter is currently supported only for HLSL. Fixes #89802
