[clang][Preprocessor] Add peekNextPPToken, makes look ahead next token without side-effects (#143898)

This PR introduce a new function `peekNextPPToken`. It's an extension of
`isNextPPTokenLParen` and can makes look ahead one token in preprocessor
without side-effects.

It's also the 1st part of
https://github.com/llvm/llvm-project/pull/107168 and it was used to look
ahead next token then determine whether current lexing pp directive is
one of pp-import or pp-module directive.

At the start of phase 4 an import or module token is treated as starting
a directive and are converted to their respective keywords iff:

 - After skipping horizontal whitespace are
    - at the start of a logical line, or
    - preceded by an export at the start of the logical line.
- Are followed by an identifier pp token (before macro expansion), or
    - <, ", or : (but not ::) pp tokens for import, or
    - ; for module
Otherwise the token is treated as an identifier.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
