ENH: Support exporting/importing of Framework targets.

  - Imported frameworks have the FRAMEWORK property set
  - Added cmTarget::IsFrameworkOnApple method to simplify checks
  - Also remove separate IMPORTED_ENABLE_EXPORTS property and just use ENABLE_EXPORTS since, like FRAMEWORK, it just represents the target type.
  - Document FRAMEWORK keyword in INSTALL command.
  - Updated IMPORTED_LOCATION property documentation for Frameworks
