Fix to make the property internalToolExecutionEnabled readable when options are merged

  - In DefaultToolCallingChatOptions, the property internalToolExecutionEnabled was set via deprecated proxyTools property which is now removed.
    - Add getter method with the prefix "get" to make the BeanWrapperImpl recognize the reader method for internalToolExecutionEnabled
    - Fix ModelOptionsUtils to recognize the correct interface method for boolean property names
