friendlier cross env test for Blob/Files and overall #29850
Description
I want to test fetch-blob agains WPT in NodeJS.
To make it more cross environment friendly could you remove this two small test document.body tests into a DOM only environment?
wpt/FileAPI/file/File-constructor.any.js

Could you also replace the FileReader with the blob.text() and blob.arrayBuffer()? NodeJS do not have a FileReader... Think the FileReader should be tested separately...

test_blob & test_blob_binary would be best if it was assigned to globalThis cuz everything runs as a module and isn't assigned to global scope.
Notices testharness have problem detecting the global scope... basically had to do globalThis.self = globalThis before loading testharness.
It would have been nice if more test where written in ESM instead...
