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.

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.

are now scoped, so that an annotation on a library or class will take effect unless shadowed by a closer `dart2js:late` annotation.

This change addresses a technical debt issue in dart2js, where
errors sometimes get reported as a binary offset location, instead
of a line/column position with contextual data from the source file.
The reason for this behavior is that dartj2s reports binary offsets
when it can't recover line/column data and show the contents of the
file. This typically happens if the file cannot be read directly
from disk.
The fix consits of adding an API to record the contents of files
that are not read directly by the compiler. We then use this API to
provide all sources collected by the CFE when parsing components
from .dill files.
Note: this CL also deletes the `autoread` feature in
source-file-provider. That feature was added for the same purpose.
The way it worked was that instead of registering source content, it
tried to read the sources from disk on-demand as errors got
reported. This doesn't always work for three reasons:
* First, we often use custom schemes (like the multi-root scheme) in
dill files to make the .dill deterministic in distributed build
systems, the autoload feature had no understanding of how to
translate those custom URIs to file URIs (that translation is only
define at the time the .dill is being built).
* Second, sometimes the files are simply not available, for example,
in hermetic build systems like bazel we have no access to those
files.
* Third, when files were found, there was no guarantee that the
contents were consistent. That is, the current version of the file
on disk could have been modified and have different contents than
those used when the .dill file was built.
I tested this manually by adding a crash in SSA and observing the
location in multiple scenarios, including running from source,
running from a .dill with file URIs, running from a .dill with
multi-root URIs, crashing in SDK locations in regular files and
patch files.
