[clang-format] Correctly annotate static and consteval lambdas

`P1169` "static operator()" (https://wg21.link/P1169) is accepted to
C++23 and while clang itself doesn't exactly support it yet,
clang-format could quite easily.

This simply allows the keyword `static` to be a part of lambdas as
specified by the addition to [expr.prim.lambda.general]

While adding this, I noticed `consteval` lambdas also aren't handled,
so that keyword is now allowed to be a part of lambdas as well
