This fixes an issue where `tuareg-opam-current-compiler` would be undefined if `opam-switch-mode` was loaded before `tuareg`.
Some Rocq users don't use OPAM, so I add a new flag that can be used to turn off loading features that depend on `opam`, such as `opam-switch-mode`.
Some OCaml users don't use OPAM, so I add a new flag that can be used to turn off loading features that depend on `opam`, such as `opam-switch-mode`.

This PR adds configuration to install and use
opam-switch-modeto manageopamswitches to thecoqmodule. The configuration is taken almost straight from PR #7806 which added the same capability to theocamlmodule. The only difference is that, unlike in theocamlmodule, we do not initialize the environment right away.Incidentally, we need to wrap this initialization inside the
ocamlmodule, or it will try to execute even iftuaregisn't loaded and produce an error.Note that this is my first PR, and that I am not very familiar with Emacs and
use-package, so I'm not very confident that commit bdb4d60 is doing the right thing; at least, it seems to work on my machine.I'm also not sure if it's fine to use the same
package!in two different, non-mutually-exclusive modules.
