Per the spec [1], a resolved promise may be “pending, fulfilled, or
rejected”, but previously V8 incorrectly used the term “resolved”
instead of “fulfilled”. This change is user-observable through the
`d8` REPL and the DevTools Console.

For keyed stores we recompute handlers when we see a new map so that
we could transition to the most general elements kind we have seen so
far. When recomputing these handlers we drop the deprecated maps.
Instead we could TryUpdate deprecated maps. This would be inline with
what TurboFan does and also may be better for performance.

The two refactorings are somewhat orthogonal, but intersect at the
class and instance type list generation, which is why it's easier to
put them in one CL.

For the removal of HasIndexedField, the removal is motivated by the
fact that is no longer necessary, and that using a flag to store this
kind of information is hacky.

For the class list changes, this is a cleanup in that we no longer
generate third-order macros, but instead normal macro lists.
There is a functional change and bug-fix in that we no longer include
abstract classes in lists that refer to instance types or maps. It's
still somewhat broken though, so I can't test abstract internal classes
yet, though. Coming in a follow-up CL.

This is a reland of 44826509.
TSan issue were fixed in https://crrev.com/c/2139574. One test
failing in the 'stress' variant is skipped for now, until we figure
out what the intended behaviour actually is.

Original change's description:
> [wasm] Debug in Liftoff by default
>
> This flips the --debug-in-liftoff flag to be on by default.
> There are still some outstanding issues with that configuration, but not
> more than with the interpreter configuration. Thus flip now, such that
> we can fully focus on stabilizing that config.
