This change adds a new HLSL 202y language mode. Currently HLSL 202y is planned to add `auto` and `constexpr`. This change updates extension diagnostics to state that lambadas are a "clang HLSL" extension (since we have no planned release yet to include them), and that `auto` is a HLSL 202y extension when used in earlier language modes. Note: This PR does temporarily work around some differences between HLSL 2021 and 202x in Clang by changing test cases to explicitly specify 202x. A subsequent PR will update 2021's language flags to match 202x.
