As advised in [1], this CL removes unnecessary Foo::Create() factory functions
which return an instance created by MakeGarbageCollected<Foo> in
//third_party/blink/renderer/modules/media{_controls, capturefromelement,
recorder, session, source, stream}, then this CL makes the callers
use MakeGarbageCollected<Foo> instead of Foo::Create() factory functions.

Additionally, this CL removed Foo::Create() in modules/installedapp as well.
