Add a library for interacting with EVM precompiles

[Thaleszh]

Is your feature request related to a problem? Please describe.
The SDK doesn't currently expose wrappers for the KiiChain EVM precompiles, making it difficult to use EVM-native modules like Identity or Compliance in Rust.

Describe the solution you'd like

• Create a precompiles/ module or crate in the SDK
• Wrap low-level eth_call or eth_sendTransaction to interact with known precompiles (Identity, Token, Whitelist)
• Include ABI files if needed and document the methods
• Add one test that calls a local node and reads identity metadata or attempts a compliance check

Describe alternatives you've considered
Using raw JSON-RPC calls, but typed wrappers offer better safety and readability.
