Nyall Dawson d3016d73d4 [processing] Add method to specify additional expression context variables
which will be available to a parameter when it is evaluated.

Specifying variables via this method is for metadata purposes only.
It is the algorithm's responsibility to correctly set the value of
these additional variables in all expression context used when evaluating
the parameter, in whichever way is appropriate for that particular variable.
