[CXF-6268] Add toolchains support to codegen-plugin

Default behavior is modified and the javaExecutable path is resolved in the
following order:
1. a 'javaExecutable' property explicitely set is used as is ;
2. if the the toolchain manager provides a 'jdk' then it is used ;
3. fallback to default behavior: ${java.home}/bin/java.
