  Merge Wasm::Instance into JSWebAssemblyInstance
https://bugs.webkit.org/show_bug.cgi?id=276963
rdar://problem/132330783

Reviewed by Yusuke Suzuki.

This patch combines `Wasm::Instance` into `JSWebAssemblyInstance` by mostly just merging the two together.
In order to make this work a couple interesting changes had to made:

1) IsoSubspaces now support variable-sized precise-only configurations. In this configuration an IsoSubspace can support variable sized objects
   that are always allocated as precise allocations. This is ok for JSWebAssemblyInstances because they are both relatively rare and typically
   quite large. One thing to note is that IsoSubpsaces in this configuration don't (currently) support IsoCellSets since those expect a max of
   eight precise allocations.

2) Wasm::Memory used to have a `HashSet<WeakPtr<Wasm::Instance>>` in order to update the cached memory bounds/base but now uses a
   `WeakGCSet<JSWebAssemblyInstance>` instead. This works because `Wasm::Memory`s are essentially tied to a single VM anyway.

3) WeakGCSet now works out of the box without a custom hasher. It uses the underlying value as the key, which is probably what people expect.
   The only constraint is that `WeakHandleOwner`s are not supported, currently. It's a little unclear how we would support more than one anyway
   since a `Weak` only supports one `WeakHandleOwner` in its `WeakImpl`

4) the `current_memory` instruction now has one more dependent load since `JSWebAssemblyInstance` doesn't hold a direct pointer to `Wasm::Memory`
   and only points to `JSWebAssemblyMemory` but `current_memory` isn't a hot instruction and hopefully we'll merge `Wasm::Memory` into `JSWebAssemblyMemory`
   in the near future.

Some other cleanup changes:

1) Add a copyright to the IPInt .asm files
2) capitalize `arraySegmentOperation` to `ArraySegmentOperation` correctly for a type per WebKit style.

In the future we should:

1) Get rid of instance GC anchoring since the JSCell is now in a register.
2) Merge `Wasm::Memory` into `JSWebAssemblyMemory`
