The clang-extdef-mapping tool can only output the real file name of the input source file. When analyzing with AST file based CTU analysis, the file name should be adjusted to the corresponding AST file, where `.ast` will be appended to the file name, and sometimes the path will even be changed. It is very inconvenient to adjust the file path with such a separated step, especially on Windows, where utility tools such as `sed` are not available.

This patch uses `Regex::sub` function to adjust the output file name for each index entry with the pattern provided by the user.
