Remove the typed array check when calling `LoopbackPort` in `PDFWorker._setupFakeWorker`
Remove the typed array check when calling `LoopbackPort` in `PDFWorker._setupFakeWorker`

With version 2.0, native support for typed arrays is now a requirement for using the PDF.js library; see PR 9094 where the old polyfills were removed.
Hence the `isTypedArraysPresent` check, when setting up fake workers, no longer serves any purpose here and can thus be removed.
