Change Fasta type inference and Kernel type checking to use the new
definition for Future flattening, which is really unwrapping (peeling
off one layer of Future or FutureOr). Use this for inferring types of
`await` expressions and return types from `async` functions.
Ensure that we are using the same notion of flattening for inference
and checking. (Maybe it was a red flag that we weren't.)
This fixes await_test so that it produces a runtime error rather than
a compile time error - see #31541.
A similar change will need to be made to the analyzer - see #31887.

- fix some discrepancies between old and new deferred loading.
* Kernel is now using the correct world impact
* For the old FE, I'm more careful about avoiding metadata nodes when mirros
are disabled as well.
* Better approximate when a constant is deferred in the kernel codegen
- make 'dump()' independent of the IR, so we can easily compare them side by
side.
- exclude primitives in kernel since we don't need to track them. I
didn't change the old front end because it is not as easy to do. I did this
change because kernel was processing many more constants than the old frontend
(the old frontend skipped constants that were never evaluated, we have no way
to do it selectively like that in the new front end).

Some additional optimization work will need to be done at the end so
that we take out these functions when they are not needed (when we

This CL fixes two minor flaws in the type inference of closure return types:
- inferReturnType needs to call _wrapAsyncOrGenerator prior to
checking whether the inferred return type is a subtype of the
context. This is necessary because for async and generator
functions, the context type is the "wrapped" type (FutureOr<>,
Iterable<>, or Stream<>).
- _updateInferredReturnType needs to perform implicit downcasts before
storing the inferred return type. This is necessary because if in
implicit downcast is added, the inferred type that should be stored
is the type that was downcast to. In order to make this work, the
"unwrapping" logic needed to be moved from
_updateInferredReturnType's two call sites into
_updateInferredReturnType itself.
These flaws were benign because they were masked by the looseness of
the future flattening operation. They need to be fixed so that future
flattening can be made more precise.

This linked in kernel service dill file will be used to load the kernel
isolate if the attempt to lookup the kernel service snapshot fails. The
kernel service snapshot is looked up in the following order.
1. If the "--dfe" option is specified, the file specified is used.
2. If the kernel service snapshot is found next to the executable,
then it is used.
3. If the kernel service snapshot is found in the "snapshots" directory
next to the executable, then it is used.

A fairly internal case, so I ended up guarding it semi-heavily with
asserts, which could go against convention, but seems fairly safe here.
Two tests: One that sanity checks some edge cases & exemplary values,
and another one that checks each combination programmatically. Together
they should be the best coverage; both the reliance of computers and
the simplicity of specific cases.
Should be very easy to pop in the void type here next.

This CL extracts parsing modifiers from parsing types so that
parseModifiers just parses modifiers and a separate call is made
to parseType.
* Discard the ModifierContext object sooner
* Remove some places where findMemberName output was being
used to determine which modifiers are present.
Currently, modifiers are parsed once by findMemberName,
again by parseModifiers, and sometimes a third time
by isFactoryDeclaration. This CL sets the stage for
improved modifier recovery and parsing modifiers exactly once.
