These AST nodes were so far internal to the CFE, but since we need to
move the pattern lowering to the constant evaluator we need to support them in the AST defined in package:kernel.

This does not necessarily enable the native null assertions by default
everywhere but it is a step on the path to get there.
- The calls to the method that reads this value are only generated in
sound null safety so even if this is true the checks don't happen
in weak null safety. Added a warning when the option is enabled in
weak null safety.
- Many DDC integrations will set the flag manually during the bootstrap.
That setting still overrides the default value being changed here.

There's been some talks about weird failures on DDC and there was
ideas that this was caused by some sort of leak (of kernel libraries).
I haven't really found any "meaningful" leaks that should be able
to cause that.
What I have found is this:
* a temporary leak where the vm seemingly gets "one behind".
That's fixed here by creating a class for the ddc batch compiler,
having things in field variables etc. It shouldn't influence results.
* a leaks via https://github.com/dart-lang/sdk/issues/51317 --- but
that's just wasted memory, I can't see how that should influence
results.
* a leak via kernels dummy nodes --- again it shouldn't influence
results (unless we're leaving dummy nodes in the output somewhere
--- which, considering I'm removing that in my test by null'ing out
the parent pointer and stuff still working I'm guessing we're not).
* another leak via some ports map after a crash, but that seems
to go away on its own (the VM cleaning it up later than I think it
should?). Again it shouldn't influence anything other than
(temporary) wasted space.
I've wired up the leak testing stuff into the DDC batch mode so that
one can go into "leak test mode" by doing `export DDC_LEAK_TEST="true"`
on the terminal (I think `set DDC_LEAK_TEST="true"` on Windows).
Then one could run test.py, say
```
python3 tools/test.py -t10000 -c dartdevk --nnbd weak -m release \
-r none --enable-asserts --no-use-sdk -j 1 co19/LanguageFeatures/
```
and attach the leak tester via
```
out/ReleaseX64/dart \
pkg/front_end/test/vm_service_for_leak_detection.dart --dart-leak-test
```
Currently this finds - if I recall correctly - 3 leaks (I think all via
the ports map stuff), but it all goes away again on it's own, so likely
another case of the VM somehow getting "one behind".

Overriding fields can change the type to remove nullability and
can also be final so they override the getters only.
For DDC that means there is an inherited setter that could still be nullable and a forwarding setter that should allow null even though
the type of the overriding field is non-nullable. With enhanced null
safety asserts enabled in weak mode there should be no failure when
setting the inherited field to null.
