Subject: Introduce per-config OUTPUT_DIRECTORY properties

We create per-configuration target properties to specify ARCHIVE,
LIBRARY, and RUNTIME output directories.  The properties override the
generic properties for the <CONFIG> configuration:

  ARCHIVE_OUTPUT_DIRECTORY -> ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
  LIBRARY_OUTPUT_DIRECTORY -> LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
  RUNTIME_OUTPUT_DIRECTORY -> RUNTIME_OUTPUT_DIRECTORY_<CONFIG>

For multi-configuration generators, the per-configuration subdirectory
normally appended to the generic output directory is not added to the
configuration-specific property values.  This allows projects to set the
exact location at which binaries will be placed for each configuration.

See issue #9163.
