Default values for TfLiteHexagonDelegateOptions

Browse Source 
This CL introduces TfLiteHexagonDelegateOptionsDefault() method that returns
an instance of TfLiteHexagonDelegateOptions with default values.
Without an API for defaults, every new field added will break consumers of
hexagon delegate, as they will be filled with garbage values.

This is also similar to TfLite GPU delegate API.
