Rm ArrayBuffer.resize polyfill when Firefox supports it by default

from #638 (comment)

According to caniuse page, the support is experimental on version 124 (current version) of firefox (can be enabled via a flag). So I think it's expected to be stable on 125. Unfortunate I couldn't find the issue tracker anywhere so I can't confirm that information.

In any way, I feel like this API is relative new on all other browsers, so it's maybe better to keep this polyfill for a while.

A small correction is that I'm not sure if Firefox 125 will have it enabled by default or not. Would you mind to change the title for clarification @mishig25 ? Something like: Rm ArrayBuffer.resize polyfill when Firefox supports it by default

Thanks in advance.

done so 👍

Update Firefox 125 is out, but support for .resize is still experimental: https://caniuse.com/?search=ArrayBuffer.resize

but support for .resize is still experimental

let's keep the polyfill until .resize is in stable mode
