feat: cross chain registry (#1439)

**Motivation:**

CrossChainRegistry contract as defined in the following TDDs:
1.
https://www.notion.so/eigen-labs/TDD-Stake-Table-Generation-19d13c11c3e0804f9c44cb5a5477fe8c#1f813c11c3e080f7bd1ede3b7cc21661
2.
https://www.notion.so/eigen-labs/TDD-Operator-Table-Transport-1f213c11c3e080c29ea5cef3ba953809

**Modifications:**

* `ICrossChainRegistry.sol`
* `CrossChainRegistry.sol`
* `CrossChainRegistryStorage.sol`

**Result:**

CrossChainRegistry
