[clang] Change representation of CurLexerKind (#70381)
Previous representation used an enumeration combined to a switch to
dispatch to the appropriate lexer.
Use function pointer so that the dispatching is just an indirect call,
which is actually better because lexing is a costly task compared to a
function call.
This also makes the code slightly cleaner, speedup on compile time
tracker are consistent and range form -0.05% to -0.20% for NewPM-O0-g,
see
https://llvm-compile-time-tracker.com/compare.php?from=f9906508bc4f05d3950e2219b4c56f6c078a61ef&to=608c85ec1283638db949d73e062bcc3355001ce4&stat=instructions:u
Considering just the preprocessing task, preprocessing the sqlite
amalgametion takes -0.6% instructions (according to valgrind
--tool=callgrind)
