    build: Port IWYU runner script to use compilation database
    
    Using Meson, we get a compilation database in the build directory, which
    makes it much easier to run IWYU. We remove the 'make iwyu' target from
    the Autotools makefile and instead port the tools/run_iwyu.sh script to
    use the compilation database generated by Meson.
