scmutil: introduce filterrequirements() to split reqs into wc and store ones
In upcoming patches where we try to implement requirements in store, we will
need a mechanism to split all requirements on some basis and decide which one
goes to `.hg/requires` and which one goes to `.hg/store/requires`.
This patch introduce a separate function for that. Filtering logic for now is
put under an `if False:`. In upcoming patches it will be removed.
