[api-major] Remove the unused encrypted property from the pdfInfo object sent from the worker via the GetDoc message

Browse source 
I recall being confused as to the purpose of the `encrypted` property all the way back when working on PR 4750.

Looking at the history, this property was added in PR 1698 when password support was added to the API/viewer. However, its only purpose seem to have been to facilitate the addition of a `isEncrypted` function in the API. That function never, as far as I can tell, saw any use and was unceremoniously removed in PR 4144.

Since we want to avoid sending all non-essential data early during initial document loading (e.g. PR 4750), it seems correct to get rid of the `encrypted` property. Especially since it hasn't even been exposed in the API for over three years, with no complaints that I'm aware of.

Finally note that the `encrypt` property on the `XRef` instance isn't tied to the code that's being removed here. Given that we're calling `PDFDocument.parse` during `createDocumentHandler` in the worker which, via `PDFDocument.setup`, calls `XRef.parse` where the `Encrypt` data (if it exists) is always parsed.
