Bug 1834703 - Return null origin of "blob:" URL containing disallowed inner schemes r=smaug,valentin

Browse Source 
Return null origin of a blob URL containing an inner URL which is not of
some schemes (https, http, file per spec) to comply with new spec changes.
Allowed schemes also include moz-extension for our own purposes.

Examples:
- "blob:blob:https://example.org/" - inner blob URL
- "blob:ws://example.org/" - inner non-http(s) URL

Spec PR: https://github.com/whatwg/url/pull/771
WPT tests: https://github.com/web-platform-tests/wpt/pull/40133

16 WPT subtests newly pass 🎉
