Recognize .cxx as a valid c++ source file extension

[premsair]

Current Behavior

Gradle core cpp-library, cpp-application and cpp-unit-test plugins does not recognize .cxx as a valid c++ file extension and does not compile the sources that end with .cxx when source property on component (library or application extensions) is configured since the source is further filtered for "**/*.cpp", "**/*.c++", "**/*.cc" files

GCC does recognize .cxx as a valid c++ file extension

The workaround is to configure the compileTask.source property directly but this is not desired since this takes away the abstraction provided by the component source property

Expected Behavior

in a given src directory (src/main/cpp) recognize .cxx files as c++ source and pass the source for compilation to compile task

Steps to Reproduce

Native support in Gradle is currently not an area of focus. There is no ETA on implementing this.
