This CL adds an interactive command line tool to analyze
heapsnapshots generated by the Dart VM.
The tool works by operating on sets of objects. It supports operations
like users, transitive closure, union, ...
An example usage that loads snapshot, finds all live objects, finds
the empty lists in them and prints retainers of the empty lists:
```
% dart bin/explore.dart
(hsa) load foo.heapsnapshot
(hsa) all = closure roots
(hsa) stat all
size count class
-------- -------- --------
43861 kb 8371 _Uint8List dart:typed_data
...
-------- -------- --------
108904 kb 400745
(hsa) empty-lists = dfilter (filter all _List) ==0
(hsa) empty-growable-lists = filter (users empty-lists) _GrowableList
(hsa) retain empty-growable-lists
There are 5632 retaining paths of
_GrowableList (dart:core)
⮑ ・UnlinkedLibraryImportDirective.configurations (package:analyzer/src/dart/analysis/unlinked_data.dart)
⮑ ﹢_List (dart:core)
⮑ ・...
```
For now the tool lives only in dart-lang/sdk.

Three improvements to the generated compile_commands.json on Windows.
1. Prevent the use of .rsp files by using `ninja -t compdb -x`.
Start using the ninja from DEPS that supports the `-x` flag.
2. Remove the `ninja -t msvc` part of the the build commands. Clangd
does not understand it.
3. Add the windows sysroots (which are set with `-e environment.x64`
in the build).
Currently, these are hardcoded to the ones shipped in depot_tools
because the `environment.x64` is non-trivial to parse.

This CL introduces a new kernel-to-kernel pass in Wasm backend to
compile `FfiNative`-annotated external functions to external functions
with `wasm:import` pragmas.
The new pass `WasmFfiNativeTransformer` extends `FfiNativeTransformer`.
Some `FfiNativeTransformer` methods made public to allow reuse in the
pass.
The conversion works like this: when we see a member like:
@FfiNative<Int8 Function(Int8, Int8)>("ffi.addInt8")
external int addInt8(int a, int b);
We generate a Wasm import using Wasm ABI types according to emscripten
calling conventions:
@pragma('wasm:import', 'ffi.addInt8')
external static WasmI32 addInt8_$import(WasmI32 a, WasmI32 b);
and convert the original member (`addInt8()`) to a wrapper function that
calls the Wasm import, converting the arguments and return values to
Dart types:
static int addInt8(int a, int b) {
return WasmI32.toIntSigned(
addInt8_$import(
WasmI32::int8FromInt(a),
WasmI32::int8FromInt(b),
));
}
Build, test, and CI changes:
- Test runner now uses `// SharedObjects=...` lines in dart2wasm tests
to pass extra Wasm modules to d8 command used to run the tests.
Support for `// SharedObjects=...` lines were already used in
native/AOT FFI tests, not added in this CL. We just start to use those
lines in dart2wasm tests.
- dart2wasm gn file updated with a target "test_wasm_modules" that
builds FFI test Wasm modules to Wasm using emcc (emscripten C
compiler).
- CI dart2wasm_hostasserts configuration updated to copy the Wasm files
generated by the "test_wasm_modules" target to the shards.

Adds a flag `--generate-prototype-events` to the dart:html generation
scripts, which causes a `prototype_events.dart` file to be generated
with EventStreamProviders and extensions for all events generated
in legacy dart:html. The generated file can be copied and pasted into `html_events.dart` to be used in the new dart:html prototype.
The script `prototype_htmleventgenerator.py` reuses as much common functionality as possible from the `htmleventgenerator.py`.
There were many edge cases to consider, like:
- de-conflicting names with different event types (e.g. ProgressEvent onError vs SpeechRecognitionErrorEvent onError)
- hiding deprecated types that don't appear in the Web IDL and haven't been needed in the glue code prototype yet
- renaming extension on-types that have been renamed from the Web IDL
- hiding custom events, which then need to be added to the prototype by hand
- prefixing some events with the correct web library

Invocations of the spec parser used to exit with an error code (245)
in the case where no files were specified. This was considered to be a
useless type of invocation, and the spec parser would print out a help
message.
However, it is perfectly possible for a Gerrit CL to give rise to
invocations like that, e.g., when the CL deletes some files and does
nothing else. Also, it causes no known issues to report a success exit
code (0) in the case where no files are specified, and hence this CL
changes the spec parser accordingly.

The `registerElement` APIs in `dart:html` are legacy APIs based on a
deprecated Web Components v0.5 specification. These methods don't work
on modern browsers and can only be used with a polyfill.
The latest Web Components specification is supported indirectly via
JSInterop and doesn't have an explicit API in the `dart:html` library.
This change marks these APIs as deprecated. We intend to remove them in
