Also cleans up and unifies some behavior across the backends:
- avoiding reinstantiating JsInteropChecks for every library
- having the native classes as a member instead of recomputing on dart2js
Now that these checks exist, we can add lib/js/static_interop_test to
the test directories the wasm trybot runs.

Add several more inlining metrics to SSA:
- getters (ellisions vs. inlines)
- setters (ellisions vs. inlines)
- intercepted length calls
- if conditions
- is checks
- late sentinel checks
After digging these are all the opportunities for optimization that I saw that I thought might be affected by changes in global inference. Open to feedback on whether any of these are unnecessary or if there's any other things worth tracking.

This reverts commit a547cfc096.
Reason for revert: With 15 shards this ends up holding too much serialized data and causes an increase in memory usage.
Original change's description:
> [dart2js] Defer deserialized CodegenResults by members.
>
> For large applications only ~60% of these objects are used. This defers their deserializtion until they're accessed in the codegen member map.
>
> In local testing on large applications this saved ~200MB of memory usage in the linker phase.

Measures inlines (and skipped opportunities) during SSA and records them within the metric framework.
This can hopefully be used as a signal into the effectiveness of changes to the global analysis phase.

Long ago the compiler had logic for reading sources via an http

keep this around anymore.

The library wasn't taken into account when handling computing class
members in the K/J-model and not handled correctly when computing
applicable selectors. This made dart2js unable to handle members with
a name private to a different library than the enclosing library.

A FieldEntity is used as the entity for generating the setter of an
instance field (when a check is required), and as the entity for the
initializer expression for a static or top-level field.
I think it is a bit clearer to have a separate method for each case
rather than one method with conditional paths.

Deletes the outline stubber as it's not necessary on any backend.
DDC should compile the entire sources and outline dill in one step.
dart2wasm operates similarly, and so only needs the modular transformer.
dart2js moves the erasure to a global transform.
Also, this CL reverts now unnecessary plumbing that was needed for the
outline stubber.

env.dart and closure.dart have a circular dependency that is a bit
hard to break, but this is a step towards starting migrating them.
It may be worth migrating the cycle of env and closure together
in one go.
That said, the definitions moved from closure.dart to
element_map_migrated.dart (e.g. ClassDefinition) seem to match
other definitions already in the latter file
(e.g. MemberDefinition)

Because the compilation wasn't `await`ed properly, metrics reporting was
failing immediately rather than first waiting for the compilation to
occur. This fixes the issue and uses the `async`/`await` API instead of
`Future` methods, which should be easier to follow.
