Bug 1997967 [wpt PR 55828] - Fix conversion from String to Blob in ClipboardItem.getType(), a=testonly

Automatic update from web-platform-tests
Fix conversion from String to Blob in ClipboardItem.getType()

String::Span8() does not return UTF-8 encoded data, but rather Latin-1
if the string has an 8-bit backing. If the string has a 16-bit backing
it returns jibberish.
