Fix failing crypto tests (#5948)

Browse Source 
* Change everything to Uint8Array

related to https://github.com/jestjs/jest/issues/14379

* Work on failing type tests

* Revert changes to custom matcher setup

* Remove last BufferArrays from tests

* Fix custom matcher type errors in vscode

* Remove errant `.buffer` calls on Uint8Arrays

* Encryption Pair should serialize Array Buffer and Uint8Array

* Fix EncArrayBuffer encryption
