Add Bip32 smart contract and adjust the key manager to utilizes it

[MoeMahhouk]

In this PR, we added the following changes:

1. Add BIP32 smart contract that only uses a hash512 precompile introduced in this PR
2. Add a new key manager that utilizes the BIP32 key derivation
3. Add unit tests for both BIP32 and the new key manager

---

NOTE

Currently, the key manager utilizes the BIP32 library to derive only hardened keys. A followup PR will tackle an API for hardened and non-hardened key derivations API either from an index or a given path

---

Testing:

• Started a local gramine-andromeda-revm instance that is running the suave-andromeda-revm with the hash512 precompile
• Started a local Suave-geth, deployed the contracts and ran the bootstrap and test-examples successfully.

Step by step to reproduce the test process:

1. adjust the deployment.json to use local host for the kettle_rpc, use your own private key and set the mrenclave/mrsigner to the local gramine-andromeda-revm
2. run the following make comands in this order: deploy, configure-all-tcbinfo, bootstrap and then make test-examples
3. all the above should run correctly without errors. (Done)
