dm: vptct: add vPTCT for post-launched RTVM

We added vPTCT support for post-launched RTVM:
1. Added a function create_and_inject_vptct. Currently, we
pass-through the whole pSRAM to one RTVM, so we will also pass-
through the PTCT to the very same RTVM. This function will
read the native PTCT from SOS and inject it into post-
launched VM's vACPI.
2. Added some definitions for vPTCT.

Tracked-On: #5330
