Add GM.xmlhttpRequest as alias of GM_xmlhttpRequest

[piquark6046]

Summary

GM_xmlhttpRequest and GM.xmlhttpRequest API cannot be used in an userscript when @grant GM.xmlhttpRequest is set instead of @grant GM_xmlhttpRequest.

The userscript works on the following environments:

• a Chromium browser (Brave 1.56.11) + AdGuard Browser Extension 4.1.57 + Violentmonkey 2.15.0
• Firefox browser + AdGuard Browser Extension 4.1.57 + Violentmonkey 2.15.0

Test page

• https://meeco.kr/Enterprise/37409313

Reference

@piquark6046 Does it reproduce with GM.xmlHttpRequest with capital H?

GM.xmlhttpRequest does not exist in specification. Old version has small h, and GM4 version has capital H.

[piquark6046]

Yes. The bug can be reproduced even if GM.xmlHttpRequest is used.
