Feature request: make JavaCC part of the cpp plugin compile action

[zosrothko]

Hello

As reported in the README

Place your JavaCC code into src/main/javacc. The generated Java code will be put under ./build/generated/javacc and will be compiled as part of the Java compile.

the javaccPlugin honnors the dependency with the java gradle plugin when generating Java classes

In the same way when generating c++ classes, the javaCCPlugin could be invoked when the gradle cpp or c plugin is active in the model.
