Shawn Nematbakhsh 0723d65ea3 console_output: Add commands for saving / restoring print mask.
Saving + restoring the channel print mask previously involved running
the 'chan' command with no parameters, then parsing the output. This
parsing is unreliable if other tasks are also writing to the console.
Add commands to save / backup the current channel mask, and later
restoring it. Typical method to limit channel mask will now be:

chan save
chan <mask>
...
chan restore

BUG=chromium:269758.
TEST=Run 'chan save' / 'chan 0' / 'chan restore' on EC console, verify
print mask is restored.
BRANCH=Peppy/Falco.
