Add EC_CMD_BATTERY_GET_STATIC v1 for zork

Some zork variants have battery model names that differ only beyond
the 7th character, which cannot be differentiated with the current
limitation of 8 characters per battery string. Introduce a new hostcmd
version that allows longer battery strings and enable it on Zork.

Because allowing longer strings through the host memory map is more
difficult and not required (because getting the full longer string
is mostly only useful for servicing), the host memory map is unchanged.
ectool is updated to use hostcmd (rather than memory map) if the new
command version is available, in order to take advantage of it.

BUG=b:171854783
TEST=ectool battery prints longer strings when supported by the EC;
     a hacked EC on morphius can return 11 characters of text.
     An EC running older firmware still works with a new ectool.
