Test and fix "/:" quoted file name handlers (Bug#30243)

Some w32 specific problems were discovered, but only worked around, as
these are not serious, and not the focus of this bug fix:
    - The w32 implementation of `insert-directory doesn't handle a nil
    SWITCHES argument.
    - `dired-compress-file' does not operate correctly if the unquoted
    filename contains a ":" (e.g., C:/foo/bar).

* lisp/files.el (file-name-non-special): Strip the "/:" from
`default-directory' for `temporary-file-directory' operation; both
arguments to `file-name-completion', `file-name-all-completion', and
`file-equal-p' operations; `buffer-file-name' for
`make-auto-save-file-name' and 'set-visited-file-modtime' operations.
Don't touch any operands of `file-notify-rm-watch' and
`file-notify-valid-p' as they receive descriptors; not file
names (this is not sufficient to fix these operations for "/:" quoted
file names though, these are fixed in a later commit).

* test/lisp/files-tests.el (files-tests--with-temp-file): Give it a
`debug' property.
