Support command versioning of new host command range
We've extended host command range from 8-bit to 16-bit. Extend
EC_CMD_GET_CMD_VERSIONS so that the host may query supported command
versions of the new host commands.
BRANCH=All
BUG=chrome-os-partner:26577
TEST=Extend 'usbpd' to version 1. Test that we can check its version.
TEST=Run 'ectool gpioget' with new ectool and old EC.
TEST=Run 'ectool gpioget' with old ectool and new EC.
