    Add tunables for input buffer

    The input machinery to read the source code independent of the lexer
    has a range of hard coded maximum array sizes that can impact performance.
    Make them tunable.

    input.cc is part of libcommon so it cannot direct access params
    without a level of indirection.

    gcc/ChangeLog:

            PR preprocessor/118168
            * input.cc (file_cache::tune): New function.
            * input.h (class file_cache): Make tunables non const.
            * params.opt: Add new tunables.
            * toplev.cc (toplev::main): Initialize input buffer context
            tunables.
