[HLSL] Add HLSL 202y language mode (#108437)
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.
