chromeos-tpm-recovery has not been used for anything in forever (see CL:238236), but it is still installed on every image. Resetting the TPM (e.g. to resolve rollback issues when reflashing an MP-signed device to dev firmware) is a common request by developers, and I get tired of always digging out the required tpmc commands manually again. Let's repurpose this script as a simple one-shot tool for developers to reset their TPM, so the next time someone asks we can just tell them 'boot a test image in recovery mode and run chromeos-tpm-recovery'. BRANCH=none BUG=chromium:419942 TEST=Ran on a Jerry, confirmed that TPM spaces were reset.
