1fa528b19f LibWeb: Keep Wasm-imported functions alive
The user is not required to keep the object alive, this commit makes it
so the lifetime of these functions is extended to match the Wasm module
it is imported into.
Fixes the crash in #907.

8b1341c77e LibWeb: Make exported Wasm functions keep the module instance alive
As it's not uncommon for users to drop the module instance on the floor
after having grabbed the few exports they need to hold on to.
Fixes a few UAFs that show up as "invalid" accesses to
memory/tables/etc.

6d4b8bde55 LibWeb: Isolate WebAssembly cache by global object
This change moves WebAssembly related data that was previously globally
accessible into the `WebAssemblyCache` object and creates one of these
per global object. This ensures that WebAssembly data cannot be
accessed across realms.

5e1499d104 Everywhere: Rename {Deprecated => Byte}String
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

This commit is auto-generated:

    $(git diff --name-only | grep \.cpp\|\.h)
  $ gn format $(git ls-files '*.gn' '*.gni')

04c094343f LibWeb+Meta: Add wrapper for the BufferSource/ArrayBufferView IDL types
These wrappers will make it much easier to do various operations on the
different ArrayBuffer-related classes in LibWeb compared to the current
solution, which is to just accept a Handle<Object> everywhere (and use
"any" in the *.idl files).
