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.

With the decision to support non-nullable locals in WasmGC as per
https://github.com/WebAssembly/function-references/issues/44 the
support in dart2wasm for forcing all locals to be nullable is no
longer needed.
This CL removes that support and cleans up some related nullability
issues. Specifically:
- Remove the `--local-nullability` and `--parameter-nullability`
commandline options. These are now always enabled.
- Clean out special cases around forced nullable locals throughout the
compiler.
- Make `thisLocal` and `preciseThisLocal` always non-nullable.
- Make `returnValueLocal` (for storing the return value of `return`
statements inside `try` blocks with `finally`) always defaultable,
since its initialization flow crosses control constructs.
- Make type argument parameters non-nullable.
- Make non-nullable `FutureOr` translate to a non-nullable Wasm type.
- Implement the "initialized until end of block" validation scheme
in the Wasm instruction validator.
- Run tests with the `--experimental-wasm-nn-locals` option. This
is likely going away soon, but for now we need it.

Methods on Object can be called on the box classes, whose Wasm
representations are not subtypes of the Object struct. Thus, the
downcast of the receiver for the preciseThis local will fail for
instances of these types.
Since the only addition in the Object struct is the identity hash
code, and this is only accessed through the _getHash and _setHash
intrinsics, no Object members need access to the precise receiver.

Fixes#49301
From https://github.com/dart-lang/sdk/issues/49301#issuecomment-1165536192
Adds referenceFromIndex to outline transformations so that the eraser
can use it to find the reference for the stub if it was already created.
This is needed when the module where the stub exists is invalidated.
Since references in other modules should still be valid, we should
attempt to get that reference.

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.

This CL fixes a number of minor JS interop issues.
* `dartify` was moved to Dart, so we can control implicit coercion from JS
* All JS types are 'correctly' handled in `dartify` though a few are boxed
as opaque types that could be exposed.
* The logic to convert a JS array is now driven from the Dart side.
* Function, Number, and Boolean can now make the roundtrip through Dart.
* The wrapper for Dart functions in JS is now a regular JS function.

The front-end variable initialization analysis considers a variable
definitely initialized if it's initialized in all `case` branches of an
"explicitly exhaustive" `switch` statement, i.e. a `switch` statement switching on an enum value where the `case` branches cover all variants
of the enum.
In order for the emitted Wasm code to validate according to the
flow-sensitive non-nullable locals validation scheme being discussed in
https://github.com/WebAssembly/function-references/issues/44 this
definite initialization must be reflected in the static control flow of
the Wasm code. Thus, such a switch statement must not have static
control flow exiting the switch statement through the (dynamically
unreachable) default case.

This adds a --platform= option to dart2wasm to read the SDK libraries
from that dill file instead of compiling them from source every time.
If the option is not given, the SDK libraries are compiled, like before.
Also adds a "dart2wasm" build target, which will build the dart2wasm
platform dill and compile dart2wasm to two AOT snapshots (with and
without asserts). The dart2wasm scripts in sdk/bin are updated to run
via these snapshots and use this platform dill.
This speeds up test runs for the dart2wasm-hostasserts-linux-x64-d8
configuration by approximately 45x.

These errors don't affect code generation, but they produce invalid
kernel which can't be serialized, so fixing them is a prerequisite for
emitting a platform dill for dart2wasm.
Also run the kernel verifier on the post-TFA kernel when asserts are
enabled. Due to the TFA tree shaking, this has a relatively minuscule
effect on the run time of the compiler.
