trunks: Made TakeOwnership re-entrant
TakeOwnership is broken up into multiple smaller calls
with each call being fully re-entrant. If TakeOwnership
exits at any intermediate step, clients can call
TakeOwnership again and have it return TPM_RC_SUCCESS.
BUG=chromium:458589
TEST=unit
TEST=trunks_client --own (exit in the middle and recall)
TEST=trunks_client --regression_test (to ensure ownership was taken
correctly)
