V8 has very limited support for inlining calls to Wasm functions
into JS. For the string/byte copy implementation it failed to inline
functions due to needing to do type conversions of parameters
in JS wrappers (e.g. to check that value is `anyref`).
=> We change wasm signatures to requires `WasmExternRef`
=> We do the type cast inside the wasm
=> This makes V8 inline the accessors
This results in roughly 3-10x faster JS<->Wasm data transfer:
WasmDataTransfer.ToBrowserString.10: -60%
WasmDataTransfer.ToBrowserBytes.10: -72%
WasmDataTransfer.FromBrowserString.1KB: -70%
WasmDataTransfer.ToBrowserBytes.1KB: -74%
WasmDataTransfer.FromBrowserString.1MB: -70%
WasmDataTransfer.ToBrowserString.1MB: -86%
WasmDataTransfer.ToBrowserBytes.1MB: -91%
(There's still plenty of room for improvement, especially on the V8 side).

Arbitrary ObjectPtr can be a non-heap object (Smi), so methods
ObjectPtr::Is* which test class id should account for Smi.
Changed ObjectPtr::GetClassId to account for Smi similarly to
Object::GetClassId. Added unsafe ObjectPtr::GetClassIdOfHeapObject
which can be used when caller knows the heap nature of the object.
This change also fixes Integer::GetInt64Value which was relying on ObjectPtr::IsSmi.

This reverts commit c1976b097d.
Reason for revert: It seems this change caused failures on Flutter
HHH bot. Example log can be found at [0]:
```
| lib/src/super_reader/super_reader.dart:615:14: Error: Final field 'showDebugLeaderBounds' is not initialized.
| Try to initialize the field in the declaration or in every constructor.
| final bool showDebugLeaderBounds;
| ^^^^^^^^^^^^^^^^^^^^^
```
Looking at the sources it seems that may be related to the
`// ignore: unused_element` analyzer directive:
```
602 /// A [SuperReaderDocumentLayerBuilder] that builds a [SelectionLeadersDocumentLayer], which positions
603 /// leader widgets at the base and extent of the user's selection, so that other widgets
604 /// can position themselves relative to the user's selection.
605 class _SelectionLeadersDocumentLayerBuilder implements SuperReaderDocumentLayerBuilder {
606 const _SelectionLeadersDocumentLayerBuilder({
607 required this.links,
608 // ignore: unused_element
609 this.showDebugLeaderBounds = false,
610 });
611
612 /// Collections of [LayerLink]s, which are given to leader widgets that are
613 /// positioned at the selection bounds, and around the full selection.
614 final SelectionLayerLinks links;
615
616 /// Whether to paint colorful bounds around the leader widgets, for debugging purposes.
617 final bool showDebugLeaderBounds;
```
So tentatively reverting this CL.

Dart classes that are structurally equivalent are currently
merged into the same recursive group to allow binaryen to distinguish
them and ptimize them independently.
This change reduces the cost of checking for structurally equivalence:
* We skip it during the discovery of available types
* We skip trivial comparisons (self, reverse, irrelevant types)
This recovers the compile-time regression mentioned in

This is a reland of commit e7658520bb
Fixes in the reland + context:
Type parameters emitted in implicit type checks on covariant mixin forwarding stubs may reference type arguments in anonymous classes. We reduce this to their mixin's implementing subclass to avoid generating RTI rules for anonymous classes.
Previous implementations would 'translate' type parameters to that of their mixed in type, but that strategy fails if the implementing subtype shuffles the order of type arguments relative to its mixed in type (demonstrated in the test - though not actually relevant in the Flutter break).
Original change's description:
> [ddc] Overhauling DDC's generic class representation.
>
> Prior to this change, DDC represented generic classes as closures over type parameters (with type arguments provided at runtime), which tightly coupled generic class definitions with their types and concrete instantiation.
>
> This rewrite decouples this representation, letting us 1) bind type information late and 2) separate generic class definitions from their instantiation.
>
> Notable changes:
> - Generic classes are now declared at top level (rather than within in closures).
> - RTIs are now passed to generic class constructors at runtime (except for JS Interop classes). Only the instantiated class's RTI is required (and it's retained up the type hierarchy).
> - Type signature resolvers are now lambdas that accept a type environment RTI at runtime. While signatures are still attached early, their instances' RTIs are now needed at runtime.
> - Generic classes, constructors, and factories are now evaluated in a 'Class' type environment.
> - An `RtiTypeEnvironment` is introduced to represent lookups on an RTI type environment bound to a parameter. These are used when evaluating type signatures and at constructor/factory bodies.
> - Type recipes now emit Class type parameters with names - but continue to emit method type parameters with de Bruijn indices. This is because indices aren't stable across subtypes.
> - Certain debugger functions now require instances (e.g.,`getClassMetadata`).
> - Adds a special flag for non-external JS interop factory constructors to emit 'true' types (versus 'any').
