Subject: [toplevel] [vernac] Remove Load hack and check supported scenarios.

Parsing in `VernacLoad` was broken for a while, but the situation has
improved by miscellaneous refactoring.

However, we still cannot support `Load` properly when proofs are
crossing file boundaries. So in this patch we do two things:

- We check for supported scenarios [no proofs open at `Load` entry/exit]

- Remove the hack in `toplevel` so the behavior of `Load` is
  consistent between `coqide`/`coqc`.

We close #5053 as its main bug was fixed by the main toplevel
refactoring and the remaining cases are documented now.
