Pure interfaces made `interface`s
implementation classes which cannot/should not be extended made `final`.
A class like `HasHMap` which provides the `Map` interface,
and no implementation except factory constructors
for internal implementations, is made `final`.
Unified {List,Set,Map}{Base,Mixin} into their `Base` class.
Deprecations are retained in comments for now, to be landed
separately. Search for '// TODO: @Deprecated'.
Tested: No new test, only adding restrictions on use.

The VM can read native asset mappings from kernel.
Previous CLs already added support to embed native asset mappings for
one-shot compilation.
This CL adds support for adding native assets mappings to kernel files
created by the frontend_server with the incremental compiler.
The frontend_server accepts a `--native-assets=<uri>` at startup and
accepts a `native-assets <uri>` message on stdin as compilation
command.
The frontend_server caches the compiled native assets library.
When a `reset` command is sent to request a full dill from the
incremental compiler, the native assets mapping is taken from the
cache and added to the final dill file.
Split of DartSDK & flutter_tools prototype to land separately.

* Add an `targetOS` argument to `pkg/vm`'s `compileToKernel`,
that contains the target operating system's name.
* Add a new `--target-os` command line argument for all binaries
that use `compileToKernel` for clients to provide the target
operating system, if known.
* Add a new`"vm:platform:const"` annotation to certain field and
getters in the Platform class.
This annotation is used to annotate static getters and fields with
initializers where the getter body or field initializer must evaluate
to a constant value if the target operating system is known. This
annotation may be used outside the Platform class and in user code.
For example, this annotation can be used on a static `String` field
that is initialized with one value if `Platform.isWindows` is true
and to a different value if `Platform.isWindows` is false.
Note: If the const functions experimental flag is disabled, then
any annotated static methods can only contain a single expression
whose value is returned. If it is enabled, then the static method
is evaluated as if it is a const function with the special
handling of annotated static fields and getters above.
* Create a VM constant evaluator that evaluates uses of static getters
and fields marked with the above annotations when a target operating
system is provided.
* Use the new VM constant evaluator in the unreachable code elimination
transformer.

- Flip flag to make strong null safety the default
- Remove code that auto detects null safety mode from source files,
it is necessary to specify --no-strong-null-safety to opt out.
- Retains sniffing of AOT/JIT snapshots and kernel files to determine
null safety mode, the opt out has to be done when generating these

Update the JavaScript bundler to maintain the state necessary for
the alternative invalidation strategy. This will provide the
javascript compiler with a single library component, so this must
handle re-combining this library with any SCC as well as keeping
the old summaries around.

When launched as a snapshot, the initial compile is slower than the existing pub approach because of a process start time of around 500 ms. When launched as a compiled executable, initial compile times are the same as the existing pub approach. Once launched, experimental results show times to produce a kernel file of at worst 1.5-2x faster than pub's solution and at best 10x faster than pub's solution. The typical workflow of making changes and recompiling results in an average of a 5x speedup with respect to pub's implementation.
Because compiler instances use a lot of memory, there is a limit on the number of active compilers that the resident server will keep alive, and will actively bring instances down when this limit is exceeded. If the user was previously compiling a given project during the lifespan of a ResidentFrontendServer and its compiler is taken down between requests, a new compiler instance will be allocated for the request. Performance is still between 1.5x-5x faster for this case when compared to pub's compile times.

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.

Fixes b/235393918
@staticInterop replaces factories with a new named node, a static
method. In order to persist this transformation in modular
compilation, this needs to be done to outlines that can then be
consumed by the source library. In order to allow erasure at the
time of 'performOutlineTransformations', coreTypes is added to that
API.
