Fast plain-text printing of kernel SSA

[cduck]

Issue: Pretty printing is very slow
Improvement: Add an option for plain-text printing (which should be very fast)

In Jupyter (and possibly other IDEs) rich color printing kernel SSA is extremely slow (slower than 10 lines per second if the kernel a few hundred lines). Most of the time, I don't care about color, I just want to see what's in the kernel quickly.

This is a workaround to print quickly. Let's add a nicer version of this to Method.print(color=False) and add a color: bool=False argument.

def fast_plain_print(kernel: kirin.ir.Method, **builtin_print_args) -> None:
    import rich, io
    with io.StringIO() as f:
        kernel.print(console=rich.console.Console(file=f, no_color=True, force_jupyter=False, force_interactive=False, force_terminal=False))
        f.seek(0)
        print(f.read(), **builtin_print_args)

I think this is partly due to rich (color rendering is handled by the terminal/notebook so it won't take much time for the program itself.) I was actually thinking about just getting rid of rich... we also have rich breaking our CI when generating notebooks with the printing.
