e1b0086a6a [wasm] Increase maximum code space on arm64
With the far jump table, we need to distinguish the maximum size of a
single code space from the maximum total code size per module. On
arm64, they differ, because we now support 1GB of code space, but each
code space is still limited to 128MB.

9cf9e82a2a [wasm][interpreter] Fix memory leak with the reference stack
This CL fixes a memory leak in the interpreter. The leak was caused by
a cycle the object graph that was rooted with a global object. The
cycle was the following:

A global handle, owned by the interpreter -> reference stack of the
Interpreter -> ref.func element (WasmExportedFunction) ->
WasmInstanceObject -> WasmDebugInfo -> InterpreterHandle -> Interpreter

With this CL we get rid of the global handle. Instead we store the stack
in the WasmDebugInfo. We then have to load the reference stack every time
we enter the Interpreter and want access the reference stack.

ae764cc31b [wasm] Fix TODO and remove bad tests
In the {Fixed} variant, the {WasmCodeManagerTest} always reserves
1GB of memory. This makes the test run OOM on many 32-bit platforms.
Instead of skipping it selectively, this CL just removes the whole
test. It caused a lot of trouble in the past, and needs two test-only
methods in the WasmCodeManager. Also, the {Fixed} variant will not be
needed any more with the wasm far jump table, since modules can always
grow then.

Drive-by: Clean up the unittests status file a bit.

importantly it fixes an issue with tracing and eventually allows for

ad83fa921b [wasm] Fix TODO and skip test on win32
In the {Fixed} variant, the {GrowingVsFixedModule} test first reserves
1GB of memory, then allocates another 1GB to add it to the module as
code. This uses too much memory on win32, making the test fail.
Before this CL, the {NativeModule} only reserved 128kB upfront (in
contrast to the actual expectation of the test).

Since all other aspects of this test are already covered by other
tests, we just skip this test on win32.
This allows us to resolve the TODO.
