Subject: [PATCH 1/2] [HLSL] Add HLSL 202y language mode
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.
