Re: [mediacapture-main] Fix language around advanced algorithm to be unambiguous.

Actually, there are several problems with the combined 'fitness 
distance' calculation text and the SelectSettings algorithm.  In the 
former 'advanced' is to be ignored, but step 5 in the latter 
specifically calls for computation of the fitness distance using the 
'advanced' ConstraintSets.  Also, in the latter we have
'3. For every possible settings dictionary of copy, compute its 
fitness distance. Discard the settings dictionaries for which the 
result is infinity, and add the remaining settings dictionaries to the
 set of possible settings dictionaries candidates

4. If the fitness distance of the best fitting settings dictionary is 
infinity, return undefined as the result of the function.'
which is clearly contradictory as written, since all infinite fitness 
distance settings dictionaries are removed in step 3.

I found it difficult to be sure that required constraints have been 
properly addressed without the current text.  I suspect that the best 
solution for now is to reintroduce the accidentally missing text on 
the initial setting of RequiredConstraints.
