Introduced a function that awaits for an additionnal rendering frame
initiated by the Owl compatibility layer processing.
By default a simple "nextTick" will handle the rendering of any widget/
component stuctures having at most 1 switch between the type of
entities (Component > Widget or Widget > Component). However more time
must be spent rendering in case we have additionnal switches. In such
cases this function must be used (1 call for each additionnal switch)
since it will be removed along with the compatiblity layer once the
framework has been entirely converted, and using this helper will make
it easier to wipe it from the code base.
