Update support for ArrayBufferView and URLSearchParams in XHR.send

Summary

Filled in null values, and corrected some erroneous entries for https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/send

Test results and supporting details

• ArrayBuffer and ArrayBufferView
  • IE: Support for ArrayBufferView was added in the same release as ArrayBuffer (10). I've previously written production code that relies on IE10 supporting UInt8Array in xhr.send().
  • Safari: I think there was a mismatch in the existing data, where the support data for ArrayBuffer was listed in the ArrayBufferView section. As far as I can tell from WebKit issues, ArrayBuffer support was added in the same release (6) as Blob and FormData support (bug 50199), while ArrayBufferView was added later in version 7 (bug 90536).
• URLSearchParams
  • Most of these updates were to align with the support data of the URLSearchParams object itself. https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams
  • IE: Doesn't support URLSearchParams at all.
  • Opera: Was listed as version 12. But overall URLSearchParams object support is listed as being added in version 36, so it can't have supported URLSearchParams in xhr.send() in version 12. I've updated Opera and Opera Android to match their respective Chrome versions for this API.
  • Safari: Was listed as not supported, but I think that was a misunderstanding of the linked bug (227477). When URLSearchParams was added in Safari 10.1 (iOS 10.3), it was implicitly supported in xhr.send() via calling .toString() on the body argument. Bug 227477 corrected the Content-Type header, and was fixed and included in Safari Tech Preview 129 / Safari 15. I tested this manually by comparing results in Safari 14.1 and Safari 15.

Looks like a sensible clean up. A couple adjustments needed for the fixes in Safari 15. Thank you!

Thanks for digging into this! There's just one small change I'd like to request, but otherwise the IE data agrees with what I've found, and the Safari data looks good to me!

Thanks for the quick adjustments, this is LGTM! 👍
