Extend and document compiler debugging utilities (#19841)
* Add two debugutils procs that native debuggers can break on use to execute commands when code of interest is being compiled. * Add GDB and LLDB programs to disable and enable breakpoints and watchpoints when code of interest is being compiled. * Extend the `intern.rst` docs regarding debugging the compiler.
