This reverts commit 09eed74a8a.
Reason for revert: Too much SDK code is not yet compliant.
Original change's description:
> Make `void` a static warning to use almost everywhere.
>
> Changed the hint to a StaticWarningCode, since that's the new spec'd
> error type and the hint is no longer needed.
>
> Added a new set of methods to test the cases.
>
> Didn't try to solve the problem generally ("all usages except ... are
> errors" means it easier, in theory, to make a ReportVoidExpressions
> style visitor that catches absolutely all types) because most of the
> work is actually about suppressing errors that are no longer needed.
> Ie, from NO_SUCH_METHOD to USAGE_OF_VOID_RESULT which means we have to
> put the void handling logic into each AST method specially anyway.
>
> Some redundant tests removed.
>
> Don't flag: ternaries, void -> void assignments, void returns in
> dynamic.

Changed the hint to a StaticWarningCode, since that's the new spec'd
error type and the hint is no longer needed.
Added a new set of methods to test the cases.
Didn't try to solve the problem generally ("all usages except ... are
errors" means it easier, in theory, to make a ReportVoidExpressions
style visitor that catches absolutely all types) because most of the
work is actually about suppressing errors that are no longer needed.
Ie, from NO_SUCH_METHOD to USAGE_OF_VOID_RESULT which means we have to
put the void handling logic into each AST method specially anyway.
Some redundant tests removed.
Don't flag: ternaries, void -> void assignments, void returns in
dynamic.

The latter was already passing (because FutureOr<void>.isVoid is true
already, which was a condition of early bailout for MISSING_RETURN).
The former was not working, but is now handled.
Unit tests for each.

The old implementation only validated a whitelisted set of use cases,
so it would often miss important subexpressions. The new
implementation is based on a RecursiveAstVisitor so by default it
visits all subexpressions; we use overrides for the specific cases
where it's not necessary to visit all subexpressions.
Fixes#31963.
