[clang][Preprocessor] Handle the first pp-token in EnterMainSourceFile (#145244)
Depends on [[clang][Preprocessor] Add peekNextPPToken, makes look ahead
next token without
side-effects](https://github.com/llvm/llvm-project/pull/143898).
This PR fix the performance regression that introduced in
https://github.com/llvm/llvm-project/pull/144233.
The original PR(https://github.com/llvm/llvm-project/pull/144233) handle
the first pp-token in the main source file in the macro
definition/expansion and `Lexer::Lex`, but the lexer is almost always on
the hot path, we may hit a performance regression. In this PR, we handle
the first pp-token in `Preprocessor::EnterMainSourceFile`.
