tpm_vendor_cmds: add command for AP RO verificationstabilize-14235.B-cr50_stab
The new command will be used for context switching to make the large
stack of the TPM task available to the AP RO verification code.
Note that we don't want the AP to be able to send this vendor command,
some extension_route_command() enhancement might be necessary.
BUG=b:199904580
TEST=tested along with AP RO verification implementation.
