Bug 1574643 - NSS changes for haclv2 r=jcj,kjacobs

This patch contains the changes in NSS, necessary to pick up HACL*v2 in D55413. It has a couple of TODOs:
* The chacha20 saw verification fails for some reason; it's disabled pending Bug 1604130.
* The hacl task on CI requires Bug 1593647 to get fixed.

Depends on D55413.
