ENH: Support exporting/importing of AppBundle targets.

  - Imported bundles have the MACOSX_BUNDLE property set
  - Added cmTarget::IsAppBundleOnApple method to simplify checks
  - Document BUNDLE keyword in INSTALL command
  - Updated IMPORTED_LOCATION property documentation for bundles
  - Updated ExportImport test to test bundles
