resize-os-window: fix '--incremental' option of 'os-panel' action

This commit addresses a few issues with the implementation of
'--incremental':
    - Unspecified settings are reset to their default value, which
      defeats the purpose of the option.
    - It is assumed that the names of options in 'LayerCLIOptions' map
      one to one with the names of fields in 'LayerShellConfig' but this
      isn't true. For example: The 'margin_top' cli option sets the
      'requested_top_margin' layer shell config.
    - When some options are set to a certain value, they force other
      options to be some value. The current implementation doesn't
      account for this.
    - The documentation is contradictory.
