battery: Expose battery_manufacture_date() as API
The newer kernels request this data.
Add the battery_manufacture_date() as a new API.
Checked the TRMs of the following batteries. They don't have any way to
query the manufacture date, so return EC_ERROR_UNIMPLEMENTED.
* bq27541
* bq27621_g1
* max17055
* mm8013
BRANCH=None
BUG=b:160784792
TEST=Hacked to print the manufacture date, on both battery present and not.
