6654efcd82 LibJS: Remove cloneConstructor parameter from CloneArrayBuffer 
This is a normative change in the ECMA-262 spec. See:
e7979fd

Note that this implements a FIXME in InitializeTypedArrayFromTypedArray,
now that shared array buffers are no longer a concern there. We already
have test coverage for the now-handled case.

13d05403ff LibJS: Move DetachArrayBuffer implementation to the ArrayBuffer object 
The spec notes that this AO is unused by ECMA-262, but is provided for
ECMAScript hosts. Move the definition to a common location to allow
test-js to also use it.

d00b79568f Libraries: Use default constructors/destructors in LibJS 
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules

"The compiler is more likely to get the default semantics right and
you cannot implement these functions better than the compiler."

e8416b603f LibJS: Accept ArrayBuffer constructor options argument 
Test262 seems to test the changes in the "Resizable ArrayBuffer and
growable SharedArrayBuffer" proposal. Begin implementing this proposal
by accepting the new options object argument to the ArrayBuffer
constructor.

de90d54be0 LibJS: Convert ArrayBuffer construction to ThrowCompletionOr 
This also allows us to create TypedArrays with an existing buffer thus
clearing up an additional FIXME in TextEncoder.

45cf40653a Everywhere: Convert ByteBuffer factory methods from Optional -> ErrorOr 
Apologies for the enormous commit, but I don't see a way to split this
up nicely. In the vast majority of cases it's a simple change. A few
extra places can use TRY instead of manual error checking though. :^)

1fba5ca8c3 LibJS: Implement the AllocateArrayBuffer() AO 
This should be used instead of ArrayBuffer::create() in most places, as
it uses OrdinaryCreateFromConstructor to allow for a custom prototype.

The data block (ByteBuffer) is allocated separately and attached
afterwards, if we didn't fail due to OOM.

d42d655853 LibJS+LibWeb+Spreadsheet: Upcall visit_edges() via Base typedef 
Let's use Base::visit_edges() when calling the base class, to prevent
accidentally skipping over anyone in the inheritance chain.

7589cc2494 LibJS: Handle possible allocation failure in ArrayBuffer(size_t) 
...by replacing it with a ctor that takes the buffer instead, and
handling the allocation failure in ArrayBuffer::create(size_t) by
throwing a RangeError as specified by the spec.

8527f00065 LibJS: Allow and check for detached ArrayBuffers 
This is required by the specification and will be used for the
$262.detachArrayBuffer method in test262.

8dc86c6aad LibJS: Bring ArrayBuffer.prototype.slice closer to spec 
The exception order was incorrect in the old implementation, and it
did not use the Symbol.species constructor as required by the spec.

4fd43a8f96 LibJS: Allow ArrayBuffer to not own its backing data buffer as well 
This is implemented as a ByteBuffer* in a variant, so its size should
only be increased by an index.
