[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] Fix incorrect constant folding of if consteval

Fixes https://github.com/llvm/llvm-project/issues/55638.

`if consteval` was evaluated incorrectly when in a
non-constant context that could be constant-folded.

Implement if consteval (P1938)

Modify the IfStmt node to suppoort constant evaluated expressions.

Add a new ExpressionEvaluationContext::ImmediateFunctionContext to
keep track of immediate function contexts.

This proved easier/better/probably more efficient than walking the AST
backward as it allows diagnosing nested if consteval statements.
