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.

This is part one of a series to merge the keyboard scan interface to
be common across all platforms.
This change just moves and renames files and APIs and removes some
read code, and sets up protocol-specific CONFIG options. It makes the
next CL which actually merges keyboard scanning easier to parse.

No functional changes; just renaming.

Now both copies of the event state live in host_event_commands.c, and
lpc / memmap just shadows the main copy.

Boot system. should see events 0x2000, 0x80, 0x08 get set and then cleared.
At U-boot prompt, type on keyboard. Should set event 0x1000 get set,
but only on the first keypress (because U-boot doesn't consume that
event).
Then from EC console,
hostevent clear 0x1000 -> see event 0x1000 clear
hostevent clear 0x1000 -> no debug output (it's already clear)
hostevent clearb 0x1000 -> see event copy B 0x1000 clear
hostevent clearb 0x1000 -> no debug output (copy B is already clear)

No code changes, just rearranging source in preparation for an
experiment to see how much the binary shrinks if we disable the
