Modularization of sagelib: Distribution sagemath-plot

[mkoeppe]

This would package all of sage.plot.

Plotting uses RDF a lot. Via #32677, #32701 we make it possible to use RDF without having to depend on GSL (non-pip-installable) and cypari2.

Via #32665, we remove dependencies on sage.symbolic. Other such dependencies such as

        from sage.symbolic.ring import SR
        # make sure both formatters typeset or both don't
        if not isinstance(tick_formatter, (list, tuple)):
            if tick_formatter == "latex" or tick_formatter in SR:

can also be easily rewritten.
