Provide getL1TokenAddress and getL2TokenAddress public actions

[danijelTxFusion]

To enable seamless bridging of assets across chains, it is necessary to retrieve the corresponding token address on the other chain for a given asset. This involves implementing two public actions to facilitate the mapping between L1 and L2 token addresses.

Implement the following public actions:

• getL1TokensAddress() - returns the L1 token address equivalent for a L2 token address.
• getL2TokensAddress() - returns the L2 token address equivalent for a L1 token address.
