tpm2: support capturing/restoring state of orderly spaces

This CL provides utility functions for copying the current state of
RAM-backed nv indices to an alt location in RAM and restoring from there
to allow saving this state over TPM reset.

BUG=b:201101365
TEST=1) create an orderly counter
     2) increment it
     3) trigger EC reset
     4) verify that the counter value was preserved
