chore: Copy subset of constants to cpp (#6544)
Browse files Browse the repository at this point in the history 
Copying all aztec constants to cpp-land caused unnecessary rebuilds of
barretenberg, since only a handful of constants are actually used. This
adds a list of what constants are actually used in cpp that are used as
a filter.
