Reland "PSM: Support PSM RLWE based message definitions in Chromium"

This reverts commit 6e670242.

Reason for reland: shell-encryption tests were failing for Win and Android, see: crbug.com/1124018. Then all tests have been disabled for all platforms except for ChromeOS, until the problem being solved from the upstream, then being rolled into Chromium.
