(WebKit::WebExtensionContext::declarativeNetRequestRuleStore):
(WebKit::computeStringHashForContentBlockerRules): Compute the hash for these content blocker rules, making sure to
append the current version of the rule translator, so when it is updated, rules will be re-compiled.
(WebKit::WebExtensionContext::compileDeclarativeNetRequestRules): Before compiling the rule, perform a lookup and check
the hash.
