EVM: enable FA withdrawals behind the feature flag

What

This MR enables FA withdrawals if the FA bridge feature is set.

Why

This integration would allow to enable FA withdrawals in the testnet while the functional is merged into master.
That way we can start doing end to end tests sooner, working in parallel on the tick benchmarks and merged bridge.

How

If FA bridge flag is set then the FA withdrawal precompile is added to the precompile set.

Manually testing the MR

make test

For running tezt scenarios:

1. Go to the tezos repo folder
2. Build octez binaries

eval $(opam env)
make build-dev-deps
make
make octez-dsn-node

3. Install eth-cli:

npm i -g eth-cli

4. Build the kernel

make -f etherlink.mk EVM_KERNEL_FEATURES=debug evm_kernel.wasm

5. Run FA withdrawal tests

dune exec etherlink/tezt/tests/main.exe -- --verbose --keep-temp -f evm_sequencer.ml alpha fa_withdrawal -i
