Lowers these extension methods to some helper functions instead of
allowInterop to improve performance and get consistent semantics.
Specifically:
- Function.toJS no longer gives you the same JSFunction when calling
toJS on the same function multiple times in the JS compilers.
- Adds fast calling syntax for functions with 0-5 args in the JS
compilers.
- Allows additional args to be passed to converted functions that
are omitted in the JS compilers.
- The static type now determines the number of args that can be
passed to the JS function in the JS compilers.
- Fixes an issue in dart2wasm where if too few arguments are
passed, the call may succeed due to conversion of undefined to
null.
- Adds throws when a user tries to wrap a JS function that
returned from Function.toJS in the JS compilers.

In most cases, the (now removed) SDK class was patched so that the constructor redirected to a platform-specific implementation of the unmodifiable view. Uses of the SDK class in the platform code could be rewritten to the more direct use of the implementation class.
The big +/- file changes are from moving the implementation classes from the patch file (typed_data_patch.dart), where they are no longer needed, to the internal file (typed_data.dart).

The existing implementation assumed, hardcoded, that the compilation
environment had an entry for any string of the form `dart.library.`+X,
with a value of either `"true"` or `""`.
This did not match the runtime behavior of the standalone VM,
which allows non-constant access to the compilation environment.
Changed to only have entries with value `"true"` for libraries
which exist.
This changes the value of `bool.hasEnvironment` or a
`String.fromEnvironment` or `bool.fromEnvironment` with a
non-default `defaultValue`.
The existing behavior was that `bool.hasEnvironment` was always true,
and that the other constructors ignored the `defaultValue`,
so most likely such tests or `defaultValues` aren't used anyway.

The patch files for these operators return a bool, whereas

possible return type, we should make them return bool for
convenience. Boolean conversion is also inexpensive on
dart2wasm, so that shouldn't be an issue.

are converted before they're compared, adding additional type
checking through the conversion.

According to the patterns spec, the pattern context type schema for a

`Object?`.
This is unlikely to make a difference in practice, since (a) cast
patterns are unlikely to be used in circumstances where the pattern
context type schema makes a difference, and (b) it takes some effort
to come up with expressions whose type inference behavior is differenc
between a schema of `Object?` and a schema of `_`.

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.
