Autogen: Detect rcc feature once during configuration

We used to detect the `rcc` features before every `rcc` list invocation
wich resulted in `rcc` be called twice for every listing operation.

Now we detect the `rcc` list capabilities once during configuration and
pass it to the cmake_autorcc target in the info file.
