Autogen: Introduce standalone RCC generator class

Introduces the standalone RCC generator class `cmQtAutoGeneratorRcc`.

Every instance of `cmQtAutoGeneratorRcc` class handles the
`rcc` invocation for a single `.qrc` file.
The class will be used in the future to allow parallel `.qrc` file
processing by calling `cmake -E cmake_autorcc <INFO_FILE> <CONFIG>`.
