cmPropertyMap: Introduce cmProp as return type for GetProperty() functions

Browse Source 
Currently properties are usually stored internally as `std::string`.
However, family of GetProperty() functions return them as `const char *` using `c_str()`.
The proposed `cmProp`, typedef'ed as `const std::string *` will expose properties
more naturally.
