adding zksync wrappers

[yashnevatia]

Holds v1.5 wrappers

I was in a nix shell derived from chainlink-integrations-pipeline

cd chainlink-integrations-pipeline
nix develop .#oneclick
# navigate to ccip dir

Steps:

# in ccip dir
# navigate to this branch 
# from root 
./contracts/scripts/native_solc_compile_all_ccip
# that should give you binaries in contracts/solc and contracts/zksolc
cd core/gethwrappers/ccip/ 
go generate go_gen_zk.go

No more changes to the ccip repo please. Use chainlink instead as we are migrating back to the Chainlink repo
