Merge bitcoin/bitcoin#24669: build: further consolidate macOS deployment

3d415215699e718b3f6eea6e3c9fb2948476f930 build: perform /Applications symlink generation in macdeployqtplus (fanquake)
dac693671928aa3fc304e6a802abfffb2f4ec8fd build: perform all .tiff copying in macdeployqtplus (fanquake)

Pull request description:

  Rather than maintaining 2 different versions of the same code (`.tiff` copying and symlink generation), consolidate to just the Python code, and use it on macOS and Linux. Previously Linux would  perform the 2 actions in the makefile, and then would still be running the `macdeployqtplus` script, so it makes sense to further consolidate deployment operations into the script.

  Guix Build (on x86_64):
