core/state: introduce code reader interface (#30816) 
This PR introduces a `ContractCodeReader` interface with functions defined:

type ContractCodeReader interface {
	Code(addr common.Address, codeHash common.Hash) ([]byte, error)
	CodeSize(addr common.Address, codeHash common.Hash) (int, error)
}

This interface can be implemented in various ways. Although the codebase
currently includes only one implementation, additional implementations
could be created for different purposes and scenarios, such as a code
reader designed for the Verkle tree approach or one that reads code from
the witness.

*Notably, this interface modifies the function’s semantics. If the
contract code is not found, no error will be returned. An error should
only be returned in the event of an unexpected issue, primarily for
future implementations.*

The original state.Reader interface is extended with ContractCodeReader
methods, it gives us more flexibility to manipulate the reader with additional
logic on top, e.g. Hooks.

type Reader interface {
	ContractCodeReader
	StateReader
}
