When a terminate_exception is raised while executing one of the promise
related jobs on the microtask queue, we don't clean up properly, leaving
the async stack in the inspector in an inconsistent state, not cleaning
up the promise stack on the Isolate, and also not resetting the global
current_microtask slot. This CL adds appropriate logic to perform the
correct cleanup.

This is a reland of 899cb34868.
The new fuzzer regression test is skipped in jitless.

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.
With this change, mjsunit tests pass on x64.
The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.
Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

Embedded builtins are now unconditionally enabled, which removes the

--jitless -> --no-opt

-> --wasm-interpret-all -> --no-asm-wasm-lazy-compilation

Note that wasm still isn't supported in jitless mode since it generates
code at runtime even with --wasm-interpret-all.
Drive-by: Fail early when trying to compile irregexp code in jitless
mode.
