Add ability to block early at launch; adapt to changes in Chromium 72+
Related issues:

- "Requests bypass uMatrix on Firefox start"
  <https://github.com/uBlockOrigin/uMatrix-issues/issues/69>

  Using same approach as with uBO:
  https://github.com/gorhill/uBloc/commit/41548be6be35

  `suspendTabsUntilReady` advanced setting added to "More" pane,
  useful only for Chromium -- the blocking of early network
  requests is enforced unconditionally on Firefox (because it
  supports returning Promises from webRequest handlers).

- "Cookies leaking temporarily"
  <https://github.com/uBlockOrigin/uMatrix-issues/issues/74>

  Changes in the webRequest API in Chromium 72+ caused uMatrix
  to fail to process `Cookie` and `Referer` headers on that
  platform.
