Add resizable ArrayBuffer examples

[chrisdavidmills]

Description

This PR adds interactive examples for the new features related to the Resizable ArrayBuffer and growable SharedArrayBuffer Stage 3 draft, which was implemented in Chrome 111+.

Note that this just includes the new features related to ArrayBuffer, not SharedArrayBuffer. I didn't add examples for those, as SAB is only available in cross-origin isolated browsing contexts. In the SAB pages that currently do have interactive examples (for example SharedArrayBuffer.slice()), the examples don't run successfully because of this, and I am concerned that it makes the pages look broken.

You're right, we should remove the examples from these pages IMO.

@chrisdavidmills We are already taking a look into SharedArrayBuffer in issue #2105. I am pretty confident that we can make cross-origin isolation work fine, so those examples don't need to be removed.

Thanks for the heads-up @NiedziolkaMichal. I'll not call for the removal of what's already there, in that case.

@wbamberg does what I've added here for the ArrayBuffer pages look OK to merge?

[wbamberg]

We don't have explanatory comments in interactive examples, they're "show don't tell". Otherwise these look great.

[chrisdavidmills]

@wbamberg ok, gotcha. I've removed the comments

[wbamberg]

👍 thank you Chris. It always feels weird asking people to remove helpful comments, and maybe it's a bad policy, but I think it matters to be consistent one way or the other.
