Add a command in delta_generator to calculate the maximum signature size

The ota generation script used to call openssl functions to get the
signature size. This is no longer viable for EC keys. So we add this new
functionality here in the delta_generator. Because the signature size
will be later used by the delta_generator to sign the payload.

Bug: 141244025
Test: call the binary with new option
