Send data for browser.storage to the UI process

https://bugs.webkit.org/show_bug.cgi?id=267782
rdar://121279041

Reviewed by Timothy Hatcher.

This patch sends the data to be added or removed from storage over to the UI process. Next and
final steps for the Storage API is to adopt the _WKWebExtensionSQLiteStore to manage the data added
with this API. This is being tracked in https://webkit.org/b/267649.

In addition, this patch adds support for browser.session.setAccessLevel. To do this, add a boolean
representing the access level to WebExtensionContextParameters so that the value can be read when
determining to expose the 'session' API.
