util/hatch: remove GBB_HWID, clean up user-visible output
* GBB_HWID is no longer used in Hatch Kconfig, so remove the code that creates the GBB_HWID and adds it to the Kconfig section * Add more information in the usage message when the cmdline params are incorrect. * Remove messages that tell the user what to do, because the top-level program that invokes this script will handle those commands, and so this script telling the user what to do is noise (and possibly harmful) * Add more information to the commit message that the script prepares for the user. * Bump script version number.

To start a new variant of an existing baseboard, we need to add
the variant into the Kconfig and Kconfig.name files for the
-baseboard. In Kconfig, we have three sections that need additional
-entries, GBB_HWID, MAINBOARD_PART_NUMBER, and VARIANT_DIR.
-
-In GBB_HWID, we need to add a HWID that includes a numeric suffix.
-The numeric suffix is the CRC-32 of the all-caps ASCII name,
-modulo 10000.
-For example, if the board name is "Fizz", we calculate the CRC of
-"FIZZ TEST", which is 0x598C492D. In decimal, the value is 1502365997,
-modulo 10000 is 5997. So the HWID string is "FIZZ TEST 5997"
-In the past, we have used an online CRC-32 calculator such as
-https://www.lammertbies.nl/comm/info/crc-calculation.html, and then
-used the calculator app to convert to decimal and take the last
-4 digits.
