Autogen: Abbreviate file paths in messages

This introduces the `cmQtAutoGenerator::MessagePath` method, that abbreviates
paths by placing a
 - "SRC:" prefix in place of the project source directory
 - "BIN:" prefix in place of the project binary directory

The method is used in `AUTO{MOC,UIC,RCC}` when paths are displayed in
messages.  This makes the messages generated by `AUTO{MOC,UIC,RCC}` shorter
and improves their readability.
