get_cmake_property is get_property with the GLOBAL scope, except that
it looks like the special VARIABLES, MACROS, and COMPONENTS properties
are hard-coded into get_cmake_property incorrectly.

This should all be moved over to cmState::GetGlobalProperty and the
new TARGETS property added there.  That method already has special
handling for a few other properties too.

Also the documentation of get_cmake_property should be updated to
mention "global" properties.
