There needs to be a way to set a board ID fields in the Cr50 RW
header. This patch adds this capability to the board signer and
release image creator scripts.
create_released_image.sh is being modified to include chrome OS
command line option parsing bash library, and a new command line
parameter is defined, --cr50_board_id. Its value is a string of three
colon separated fields, <board id>:<board id mask>:<board id flags>,
where
<board id> is a 4 character ASCII string, the RLZ board code
<board id mask> and <board id flags> are two hex values, without
preceding 0x.
This value is passed to the bs script through environment variable
CR50_BOARD_ID (to be in sync with the bs script taking already
optional parameters like H1_DEVIDS from the environment).
The bs script is slightly refactored, code modifying the manifest to
splice in the device ID nodes is put into a function, and code adding
the board ID nodes to the manifest is also included in the new
function.
The three fields of the CR50_BOARD_ID string are converted to integers
and added to three nodes in the manifest (board_id, board_id_mask, and
board_id_flags respectively).

BUG=b:62294740
TEST=created a released image image using
create_released_image.sh --cr50_board_id RXXX:ffffff00:ff00 \
<rest of parameters>
using the modified usb_updater (under a different patch) verified
that the header fields have been created as expected.
