Autogen: Add cmQtAutogenGlobalInitializer::Keywords class

Browse Source 
The new `cmQtAutogenGlobalInitializer::Keywords` class instance is bound to
the lifetime of the `cmQtAutogenGlobalInitializer` instance.  Global static
const strings would be allocated at program start and deallocated at program
end.  Keeping keyword strings alive only in the context where they're
needed helps to reduce the memory footprint.
