MultiOnRamp token transfer fee config

[RayXpub]

Motivation

Implements per destination chain token transfer fee configs in the EVM2EVMMultiOnRamp, which allows the OnRamp to support more than one destination chain configuration.

Solution

• TokenTransferFeeConfig is now per destination chain per token
• added a TokenTransferFeeConfigArgs containing:
  • A destChainSelector
  • A TokenTransferFeeConfigSingleTokenArgs nested struct with token + TokenTransferFeeConfig

Out of scope:

• Full contract coverage
