This adds the dart:_macros library to the SDK and adds support for accessing dart:_macros from package:macros. The library is not used yet.
This change is needed as a prestep to adding the package:macros and using it in the CFE and analyzer, and needs to be rolled in as the checked in sdk before package:macros can be supported.

Closes https://github.com/dart-lang/sdk/issues/54138
Adds a helper to do better type-checks so that users don't
accidentally using is checks or have to manually do the right
typeof or instanceof checks. In order to do this, there is
some refactoring to make ExportCreator a SharedInteropTransformer
(as it's shared across all backends) so that we can reuse an
existing visitor. In the same class, we remove unnecessary setting
of parent pointers. We should clean up the fileOffsets as well,
but dart2js verifies that those are set, so we keep them as is
for now. Also adds some static errors for edge cases.

* Replace `.whereNotNull()` with `.nonNulls` which is now in Dart core.
* `.firstOrNull`, `.lastOrNull`, `.singleOrNull` and `.elementAtOrNull(i)` are also in Dart core and even under the same name, so simply drop the import of 'package:collection' whenever possible.

Fixes the for loop lowering to JavaScript when there are function
expressions in the loop initialization, condition, or updates.
Manually assign source mapping information on js_ast nodes to
make stepping in the Dart debugger make as much sense as possible.
With these mappings three steps are required on each loop variable
on each iteration but it ensures that the mapping always points to the
variable instead of some random line of code in or around the original
for loop.
Fixes the failure on language/loop/for_variable_capture_test.

This allows using the new scope finder and facilitates expression
compilation with and in extension types.
For now the script uri is optional (and only passable in the new json
input via package:frontend_server), and only if the script uri is passed
we'll use the new scope finder.
Flutter etc should be updated to pass the new data.

Updated the ddc canary implementation to handle variance subtyping.
Variance subtyping is currently broken on DDC. This CL emits a runtime call to `addTypeParameterVariances` from `rti.dart` to annotate the type parameter variances of each interface that's appeared in type recipes. The rest of the subtyping algorithm already exists from the Dart2JS implementation, so the variance feature should be working correctly now in DDC with these changes and after the switch to canary by default.
Existing tests now pass: language/variance/variance_in_subtyping_test, language/variance/variance_inout_subtyping_test

Previously we would encode the type of the value returned in `async`
functions as the field `futureValueType` on `FunctionNode`. For all
other kinds of functions, such as `sync`, `sync*`, and `async*`, that
field would be null. This CL renames `futureValueType` into
`emittedVAlueType`, and for functions of kinds `async`, `sync*`, and
`async*` that is expected to be the type of values emitted via
`return` or `yield` statements. For `sync` functions that field is
supposed to contain `null`.

Update source code in tests to be migrated to null safety. Tests are
still running in unsound null safety.
In most cases types are now inferred to be non-nullable so the code that
makes expressions to be seen as nullable now require `as dynamic` to
allow them to compile.
Update nullable inference logic to recognize `.toString()` on a String
as non-nullable in code that has been migrated to null safety.

DartType.extensionTypeErasure can be used by backends to easily

Adds simple method inlining for select patterns only in the dart:_rti
library as an optimization. This helps avoid chains of costly
accesses method calls that in the end simply perform a single
operation and return the result.
For example and snipet from the compiled SDK before:
```
if (_rti._isString(object)) {...}
```
and after:
```
if(typeof object == "string") {...}
```
