Entering a submodule clears GIT_DIR and GIT_WORK_TREE, as it must: they
say where the superproject is. But the stack we push the superproject
onto so that escape brings us back only held its path, and for a repo
opened with --git-dir/--work-tree the path leads nowhere — git can't
find a repo there. Escaping out of a submodule of a dotfile repo failed
with "not a git repository", or, if some unrelated repo happened to lie
above the work tree, quietly switched to that one instead.
Push the environment onto the stack along with the path, taken from the
repo paths rather than from the process env, so that it also covers a
repo we worked the location out for ourselves.

git finds a repo by looking for a .git in the directory a command runs
in. Lazygit runs its commands in the work tree, so that normally works —
but not when the git dir lives somewhere else entirely, which is what
core.worktree and --work-tree are for. Lazygit chdir'd into such a work
tree and then ran commands that couldn't see any repo from there, so
opening a repo with core.worktree set panicked on startup. It only
worked with --git-dir because that leaves GIT_DIR in the environment for
every command to inherit.
Work out at startup whether git can find the repo from its work tree,
and when it can't, put GIT_DIR and GIT_WORK_TREE on every command the
repo's builder produces. As with the working directory the builder pins
(527124d0e0), these also go into the process env — subprocesses don't
come through the builder — but the commands don't read them from there,
because the process env belongs to whichever repo we have switched to
since.
Working out whether git can find the repo means asking git, rather than
reading the .git file, whose contents can spell the same directory
differently than git does. The extra query is skipped for a repo whose
git dir is simply its .git directory, which is nearly all of them.

GIT_DIR and GIT_WORK_TREE tell git where our repo is, and every command
we run inherits them — including the ones we point at a submodule or
another worktree. git resolves those against our repo instead, and says
nothing about it: with GIT_DIR set, `git -C mysub log -1` reports the
superproject's commit. So opening lazygit with --git-dir/--work-tree
quietly broke resolving submodule conflicts, stashing and resetting a
submodule, and detaching another worktree; the worktree list came back
claiming every worktree shared our git dir.
Drop the two variables from the commands that address another repo.

This was on oversight on my part: I assumed that the --work-tree arg was
always intended for use with linked worktrees which have a .git file
pointing back to the repo.
I'm honestly confused now: seems like there are three kinds of worktrees:
* the main worktree of a non-bare repo
* a linked worktree (with its own gitdir in the repo's worktrees/ dir)
* a random folder which you specify as a worktree with the --work-tree arg
I'm pretty sure the --work-tree arg is only intended to be used with this
third kind or workree
There are quite a few paths you might want to get e.g. the repo's path, the worktree's path,
the repo's git dir path, the worktree's git dir path. I want these all obtained once and
then used when needed rather than having to have IO whenever we need them. This is not so
much about reducing time spent on IO as it is about not having to care about errors every time
we want a path.
