Overhaul Makefile binary and release worflows

* Incorporate changes from abandoned #9918: Use dedicated `bin`
  sub-directories for `windows` and `darwin` when building
  `podman-remote`.  The linux flavor remains under `bin` as before.

* Fix MacOS Documentation-generation for release-packaging.
  The `install-podman-remote-%-docs` target requires local execution
  of `podman-remote`, but it was assuming GOOS=linux.  Fix this
  by dynamically discovering the local OS/architecture type while
  still permitting cross-building of MacOS binaries under Linux.

* Unify temporary directory/file behavior to use a common template.
  In case of left-over temporary items left in the repository,
  update the `clean` target accordingly to remove them.

* Fix broken podman-remote-static and MacOS release archive targets
  mismatching the `podman-remote-%` target.  Disambiguate this target
  for all platforms by spelling each out in full, instead of using
  a wild-card recipe.

* Fix Windows-installer target to properly recognize existing
  output files and not constantly rebuild every time.

* Include the podman version number in the Windows-installer target
  in case a user downloads multiple releases.

* Include a subdirectory containing the podman version number for
  both `tar.gz` and `zip` targets.  This prevents users clobbering
  existing directories when un-archiving from releases.
