When running analyzer on flutter and it's transitive sources, it consumes around 480 MB of memory. The [ImportedElement] class is an intermediatey wrapper around an [Element] and a boolean that is mostly false. This CL removes the [ImportedElement] class and stores the boolean side-information alongside the element in [PrefixScope] and [PrefixScopeLookupResult]. This saves around 15.5 MB of memory.
