Status output related to OBS configuration is prefixed with the string
"OBS" and added padding for enabled and disabled features. This padding
was not aligned between platforms.
By moving the padding and prefix decoration into its own function,
both elements are controlled in a single place. CMake scripts were
changed to use this new function `obs_status` instead of using CMake's
`message` function directly.
Windows and Linux do not require a contained application bundle to run
and debug OBS - as such targets can and should be copied independently
from the main OBS application target.
Also silences the output of the `install` step that sets up those files.
