[analyzer] Remove the [ImportedElement] class

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.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
