cr50: add TPM vendor-specific commands to support EC-EFS2
Based on the design in go/ec-efs2, this patch adds two TPM
vendor-specific commands:
- VENDOR_CC_GET_BOOT_MODE
- VENDOR_CC_RESET_EC
BUG=b:141578322
BRANCH=cr50
TEST=tested with EC-EFS supporting EC/AP firmware.
With CR50 dev image, tested with gsctool on Octopus and Helios
by sending each of new vendor commands.
Checked flash_ec working on Scarlet in bitbang mode.
