[Clang] Modify Parser::ParseLambdaExpressionAfterIntroducer to check whether the lambda-declarator is valid
...
We had a couple of crashes due to invalid lambda trailing return types that
were diagnosed but not treated as errors during parsing. So now in
Parser::ParseLambdaExpressionAfterIntroducer(...) after ActOnStartOfLambdaDefinition(...)
we also check if the lambda-declarator is invalid and if so we end up in ActOnLambdaError(...).

[clang] Use -std=c++23 instead of -std=c++2b
...
During the ISO C++ Committee meeting plenary session the C++23 Standard
has been voted as technical complete.
This updates the reference to c++2b to c++23 and updates the __cplusplus
macro.
Drive-by fixes c++1z -> c++17 and c++2a -> c++20 when seen.

[clang] [PR49736] [C++2b] Correctly reject lambdas with requires clause and no parameter list
...
This fixes http://llvm.org/PR49736 caused by implementing http://wg21.link/P1102 (https://reviews.llvm.org/rG0620e6f4b76a9725dbd82454d58c5a68a7e47074 ), by correctly allowing requires-clause only:
1) directly after template-parameter-list
2) after lambda-specifiers iff parameter-declaration-clause is present (2nd kind of lambda-declarator)
