Prevent stale servers when using eglot-extend-to-xref
A weak-valued hash-table is not enough to guarantee that a reference
to a zombie server in eglot--servers-by-xrefed-file variable won't
survive long enough to confuse the next call to eglot--current-server
in some buffers.
So, before this fix it was common to get "Process EGLOT ... not
running" errors if some xref-extended buffers (like system libraries)
were open and M-x eglot-reconnect was issued. This should be
prevented now.
Note however, that even after this the eglot-extend-to-xref logic is
still flawed. For example, if a buffer for the xref-extended buffer
happens to be already visited by the time M-. is issued to navigate to
it, Eglot won't be activated. A half-decent workaround is to kill the
buffer and re-visit it.

Use make-directory handlers uniformly
Formerly, the code supported both make-directory and
make-directory-internal handlers. This led to confusion and meant than
in a few cases (nnmaildir, ido) remote directories could not be used in
some cases. Fix this by using only make-directory handlers.
Perhaps there used to be a reason for why there were both
make-directory and make-directory-internal handlers, but whatever that
reason was, it seems to have vanished even before now.
There is no longer any need for make-directory-internal handlers, as
the few remaining callers that use make-directory-internal do so only
when there are no handlers. However, this change keeps the existing
