Add backwards compatibility methods from FunctionCallingOptionsBuilder
to the Builder interface in FunctionCallingOptions. This allows users
to gradually migrate from the old builder style (with* methods) to the
new style while maintaining the same functionality.
Each deprecated method is marked for removal in 1.0.0-M5 and includes
proper Javadoc directing users to the new method names. The methods
are implemented as default methods that delegate to their new
counterparts.
