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
duplication.
Also gave the methods a quick overhaul for formatting,
removing uses of `late` and unnecessary element accesses,
and some general tweaks.

Pure interfaces made `interface`s
implementation classes which cannot/should not be extended made `final`.
A class like `HasHMap` which provides the `Map` interface,
and no implementation except factory constructors
for internal implementations, is made `final`.
Unified {List,Set,Map}{Base,Mixin} into their `Base` class.
Deprecations are retained in comments for now, to be landed
separately. Search for '// TODO: @Deprecated'.
Tested: No new test, only adding restrictions on use.

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.

Original change's description:
> [vm] Remove tcmalloc and malloc profiler.
>
> The standalone VM originally began statically linking tcmalloc to work around bugs in the system malloc for Fiber. Later it used tcmalloc's hooks to implement a profiler, but this is rarely used since it is only available in debug mode, misses early allocations, and often misses late allocations from an exhausted sample buffer. Removing it altogether avoids build complexity around which combinations of compiler/architecture/sysroot support tcmalloc, and reduces binary size.
