- `[[Module]]` pointing to the `WasmModuleObject`, allowing the
developer to find the module to an instance no matter where in
DevTools front-end the instance is inspected.
- `[[Functions]]`, `[[Globals]]`, `[[Memories]]`, and `[[Tables]]`
are shown (when they aren't empty), allowing developers to inspect
the entities within an instance no matter where in DevTools front-end
it's inspected.
This also updates the _Module_ scope for Wasm frames to show the entity
containers (`functions`, `globals`, `memories` and `tables`) in addition
to the `instance` and `module` to make it easier accessible (fewer
clicks to get there), but also to align it better with the _Add property
path to Watch_ and _Copy property path_ features (since exactly the same
names are exposed via Debug Evaluate on Wasm frames).

This CL fixes a bug in the code generation for I32AtomicCompareExchange
in Liftoff on ia32. The problem is the inconsistency that
LiftoffAssembler::PeekToRegister(...) introduces to the cache state.
PeekToRegister loads the value from the value stack into a register, but
does not pop the value off the stack. When the value was already stored
in a register, the use counter of that register gets decreased, even
though the value is still on the stack.
The problem arises when this register later gets reused, which is
necessary unfortunately on ia32. When SpillRegister is called for this
register, all stack values that are stored in this register get written
to memory. SpillRegister uses the use counter of the register to detect
when the register was spilled to all stack slots that were cached by
this register. However, as described above, the value stack and the use
counter are inconsistent at that moment, so SpillRegister finishes
early and does not spill the register to all stack values, and this
causes the bug later.
With this CL the decrement of the use counter gets delayed until when
the value actually gets popped off the stack.

This change unifies the locals, stack, and globals objects exposed for
WebAssembly frames via the Scope view and via DebugEvaluate to use the
same underlying objects (implemented via interceptors). This also
means that for locals and globals we now consistently expose names
prefixed by a dollar symbol everywhere.
Drive-by-fix: Move the debug::ScopeIterator implementation for WasmFrame
into debug-wasm-support.cc, so WebAssembly scope details are all found
in one place instead of scattered around the code.
Drive-by-cleanup: Rename GetJSDebugProxy to GetWasmDebugProxy for
consistency. GetJSDebugProxy is a bit misleading, since the debug proxy
is not about JavaScript, but just exposed to JavaScript.

Previously the Debug Proxy API that's exposed on Wasm frames by
Runtime.evaluateOnCallFrame() was implemented via actual JSProxy
instances. That means that all entities such as "memories", "tables",
"stack", "globals", etc. were JSProxy instances with "get" and "has"
traps. But that has a couple of down-sides:
1. In DevTools front-end, the proxies are shown as JSProxy, which is not
very useful to developers, since they cannot interact with them nor
can they inspect their contents. And the object preview also only
shows "Proxy {}" for them.
2. The performance doesn't scale well, which becomes a painful
bottleneck with larger Wasm modules that contain hundreds of
thousands of functions or globals.
3. We cannot use the JSProxy instances in the Scope view (for the
reasons outlined in 1.) and hence we have different logic to provide
Scope values than values in the rest of DevTools, which led to subtle
but annoying bugs and inconsistencies.
This also changes the "locals" implementation by querying the values
ahead of time, similar to the object exposed to the Scope view, instead
of on-demand, since the "locals" object might survive the current
debugger pause and peeking into the stack afterwards would read invalid
memory (and might even be a security issue). For being able to change
locals we need to look into a similar solution as what we have for
JavaScript locals already. The expression stack already works this way.
For performance reasons (especially scaling to huge, realistic Wasm
modules), we cache the per-instance proxies ("functions", "memories",
"tables" and "globals") on the WasmInstanceObject and reuse them (which
is safe since they have a `null` prototype and are non-extensible), and
we also cache the proxy maps (with the interceptors) on the
JSGlobalObject per native context.

We were incorrectly clearing the high reg from the list of regs to load.
The intention was to prevent double (and incorrect) loading - loading
128 bits from the low fp and the loading 128 bits from the high fp.
But this violates the assumption that the two regs in a pair would be
set or unset at the same time.
The fix here is to introduce a new enum for register loads, a nop, which
does nothing. The high fp of the fp pair will be tied to this nop, so as
we iterate down the reglist, we load 128 bits using the low fp, then
don't load anything for the high fp.

When AVX2 is available, we can use vbroadcastss. On AVX, use vshufps,
since it is non-destructive. On SSE, shufps is 1 byte shorter.

Previously we had introduced a special `v8::internal::WasmValue` type
which we used to expose Wasm values to the Scope view in Chromium
DevTools. The problem however is that these values cannot be exposed to
JavaScript (and in particular not to Debug Evaluate), which means that
particularly for v128 and i64 we have inconsistent representations
across the various parts of DevTools.
This change removes the `wasm` type from the RemoteObject and all the
adjacent logic, and paves the way for a uniform representation of Wasm
values throughout DevTools. For i64 we will simply use BigInt
consistently everywhere, and for i32, f32 and f64 we'll just use Number.
For externref we will represent the values as-is directly. For v128
values we currently use a Uint8Array, but will introduce a dedicated
WasmSimd128 class in a follow-up CL.

There's a bit more work to do to add support for import assertions for
dynamic import(). This is the first of a series of changes to do that.
This adds parser support for the form of import() that takes import
assertions per https://tc39.es/proposal-import-assertions/#prod-ImportCall
A future change will pass the assertions expression along to
Runtime_DynamicImportCall where the assertions will be unpacked and
filtered per Isolate::supported_import_assertions_.

Previously, for wrapper/wrappable pairs, only JS object size was
accounted for. With this change, the C++ part is also accounted for.

When --harmony-dynamic-import was removed in
https://chromium-review.googlesource.com/c/v8/v8/+/2509942 it looks
like we were left with some redundant invocations of
RunParserSyncTest/RunModuleParserSyncTest in ImportExpressionErrors.
This removes them.

This implements the spec change in
https://github.com/tc39/ecma262/pull/2164
Making TA elements configurable has interaction with delete. While
the elements are configurable, they are only "deletable" via detaching
the underlying ArrayBuffer, not via `delete`. That is, `delete ta[idx]`
for an in-bounds `idx` still returns false.
