Create Filters class to store filter functions

Enhanced the generated code to now store the filter functions within an
array contained in a struct similar to other configured parameters.
This allows the generated property watches to use an index within that
array to access a pointer to a Filters class containing a given set of
filter functions. The set of filter functions would then be applied
against all the properties being watched.

Tested:
    Generated code provides structure needed to access filter functions
    Filter functions filter property values that fail the filter(s)
