Adds tests for the following cases:
- Type arguments to createStaticInteropMock
- Missing members in implementing class
- Members that need to be implemented through inheritance
- Members that implement through inheritance and mixins
- Implemented members are correct subtypes
- Static checker checks for potential extension conflicts

Static class members could technically be mapped to a name with dots,
but in the early days of JSInterop we thought this was not necessary
since it could also be modeled as a top-level member or by adding
additional classes and exposing the member as a simple name on a deeper
class.
This invariant was assumed by DDC (which crashed if this was not the
case) and ignored by dart2js.
This change adds a static check to ensure both compilers act
consistenlty.

Some JS functionality is only exposed through operators, such as
implicit type conversions and BigInt arithmetic. Other than requiring
some minor additions for the exponentiation (`**`) operator, supporting
these through `dart:js_util` is trivial.

For `asyncExpectThrows`, instead of taking a function,
then checking if that function can be called with zero arguments,
and then immediately calling it and checking that it returns a future,
just take the future as argument.
Since synchronus errors from calling the function were not caught
anyway, doing the entire `Future` computation directly shouldn't
change behavior.
Also make `asyncExpectThrows` and `Expect.throws` return the caught error,
so that you can use normal `Expect.something` checks on it afterwards,
instead of doing that in the `check` function.
That basically makes the `check` function unnecessary (but hard to remove
with the existing test corpus using it heavily).
This makes some uses of the `asyncExpectThrows` function slightly more
complicated, those that have no other way to create a future than calling
the argument function anyway, but other uses become simpler
when they can avoid adding the function wrapper.
TEST= Refactoring. If the tests keep running, it's successful.

Changes 'is' checks for JS types such that it no longer does an
instance of check and instead only checks to see if the object
in question is a JS object or appropriate subtype. This means that
any two @JS objects will pass an is check and therefore can be
casted as one another. This makes it consistent with expected
behavior and dart2js.
Also amends the README to reflect the unified behavior.
