This field was supposed[1] to replace Stack.asyncCausalFrames but IDEs
and other service protocol users never adopted it.
The mechanism for collecting awaiterFrames and asyncCausalFrames
was originally considerably different, but we have since unified
both[2] after we switched to lazy async stack traces[3].
Today the only differences between the two are:
- asyncCausalFrames represens async gaps explicitly, while
awaiterFrames does not;
- when asynchronous function is running its synchronous part
before the first suspension awaiterFrames will still represent
the corresponding frame as an asynchronous activation, while
asyncCausalFrames will treat the same frame as regular frame.
Consequently having this field does not add any value.
This CL removes it from the response and updates all tests to
test against asyncCausalFrames.

TypeRef type wraps around another type and it was used to represent
a graph of recursive types. After [0], the only use of TypeRef is
for TypeParameter.bound which may indirectly reference the same
TypeParameter.
This change replaces TypeParameter.bound with TypeParameter.owner and
removes TypeRef entirely. Various parts of the VM no longer need to
handle and support TypeRefs.
TypeParameter.owner can reference a FunctionType, Class,
or, as an optimization, it can be set to null in order to share
class type parameters among different classes.
With the exception of the 'TypeParameter.owner' back pointer,
VM types are now not recursive and can be visited without
additional tracking.
Caveats:
* Generic FunctionType cannot be cloned in a shallow way:
when copying a FunctionType, type parameters should be cloned too
and their owners should be updated. For that reason,
a mapping between 'from' and 'to' function types
(FunctionTypeMapping) is maintained during type transformations
such as InstantiateFrom.
FunctionType::Clone is used instead of Object::Clone where
appropriate.
* When testing types for subtyping and equivalence, mapping
between function types is passed to make sure
type parameters belong to the equivalent function types.
* IL serializer needs to serialize function types as a whole before
serializing any types potentially pointing into the middle of a
function type (such as return type 'List<Y0>' pointing into
the middle of a function type 'List<Y0> Function<Y0>()').

Makes `Iterable` a mixin class with a `const` constructor,
and `IterableBase` and `IterableMixin` (to-be-deprecated) aliases
for it.
Combining everything in one place avoids (some) code

removing uses of `late` and unnecessary element accesses,
and some general tweaks.

- Instead of a vague error message, the call site whose target is missing is now part of the stack trace and the name/kind of the missing target is part of the exception message.
- If the missing target is on a branch not taken, things properly succeed.

The Windows and MacOS file system can be case insensitive, so the following
two URIs can be equivalent:
- file:///c:/foo/bar
- file:///C:/Foo/Bar
Since it's possible for tooling to request a mapping for a URI that
isn't an exact case-sensitive match to that found in the URI mappings
cache, requesting a mapping for the inexact match will fail even though
the paths are potentially equivalent.
This change allows for lookupPackageUris and lookupResolvedPackageUris
to correctly handle paths that are not case-sensitive matches to entries
in the URI mappings cache on Windows and MacOS.
