Chromium requires that all code that waits on a sync primitive be annotated with ScopedAllowBaseSyncPrimitives(ForTesting). Webrtc already imports ScopedAllowBaseSyncPrimitives. ScopedAllowBaseSyncPrimitivesForTesting is equivalent but can only be used in tests and doesn't required adding a friend declaration to thread_restrictions.h. Previously, the code that is annotated with ScopedAllowBaseSyncPrimitivesForTesting in this CL didn't fail because it ran on a TaskRunner annotated with the deprecated WithBaseSyncPrimitives() trait (cf. https://cs.chromium.org/chromium/src/content/renderer/media/webrtc/task_queue_factory_unittest.cc?l=23&rcl=362f3723ac358d932ea2e3af65512a1243697a31).
