Subject: [PATCH] [llvm-cgdata] Remove GENERATE_DRIVER option

This tool shouldn't be used in the driver build until it is converted to
use `OptTable` for option parsing, otherwise the `cl::opt` options might
conflict with options in other tools resulting in link failures.

This is a reland of #100066.
