Simplify and improve `MethodInvocationResolver._resolveReceiverDynamicBounded`

This change makes the following improvements:

- The setter for `nameNode.staticElement` is always
  invoked. Previously it was only invoked when storing a non-null
  element. In principle this shouldn't make a difference (since static
  elements default to `null`), but it should hopefully make the code a
  little easier to reason about.

- In the case where the `receiverType` is `InvalidType`, no other
  resolution is attempted. Previously, in this case, an attempt was
  still made to resolve the method invocation to a member of `Object`,
  which kind of went against the intended behavior of
  `InvalidType`. Also, if a matching member of `Object` _was_ found,
  then `nameNode.staticType` would get set more than once, making it
  more difficult for the reader to understand what the code was doing.

- In the case where the method invocation resolves to a method of
  `Object`, `nameNode.staticType` and `node.staticInvokeType` are set
  to the type of that method. Previously they were not set at all in
  this case (but they were set in all other cases).

In addition the logic is more straightforward, since the various AST
properties are always set in the same order by straightforward inline
code.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

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

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).
