[DNR] Add rule filter for get dynamic/session rules APIs

The declarativeNetRequest.getSessionRules and
declarativeNetRequest.getDynamicRules APIs return a list of the
extension's current declarativeNetRequest rules. Up to 5000 rules can
be returned[1]. The rules are returned in an array not sorted by rule
ID.

Quite often, an extension will only need to inspect a specific
rule. This is painful, since all returned rules need to be checked for
the desired rule ID, until a match is found or the rules are
exhausted. In the worst case, this means iterating through 5000 rules
to find that the rule isn't present.

Let's add an optional filter argument to the APIs that allows the
caller to specify rule IDs to filter the results by. For the above
example use-case, one rule ID can be specified at call time and then
the length of the returned array can be quickly checked.
