[Access] Refactor executionNodesForBlockID by encapsulating its parameters into a struct

[UlyanaAndrukhiv]

Closes: #6497

Note: #6468 should be merged first.

Context

This pull request introduces a new struct, ExecutionNodeIdentitiesProvider, which encapsulates the parameters previously passed around multiple functions. This struct is initialized during instance creation and includes fields for executionReceipts, state,preferredENIdentifiers, fixedENIdentifiers and other relevant data.

Changes:

• Created a new ExecutionNodeIdentitiesProvider struct.
• Refactored executionNodesForBlockID and related functions to use the new struct instead of individual parameters.
• Updated relevant unit tests to reflect the changes in function signatures and verify the new implementation.
