CBI: Add rework_id fieldstabilize-rust-13795.B-main
This field will be used to describe all the reworks performed on
a board which includes the mandatory, optional and feature reworks.
Also modified existing command handlers under ectool and cbi-util tool
to support 64 bit length data.
Includes build fix for targets where long int is not 64 bits.
BUG: b:170385859
BUILD TEST:
make BOARD=<BOARD_NAME> -j;
make runfuzztests
make runhosttests
