chore(sequencer): refactor fees

[ethanoroshiba]

Summary

Added trait for fee components to allow generic usage of them.

Background

Previously, there was a lot of boilerplate required when testing fee components, since we are usually testing them for each and every action. Additionally, this introduces a lot of room for human error, since it's easy to mismatch an action and its associated methods. This change aims to rely more heavily on trait methods and helper functions, so that generic types can be used to eliminate boilerplate and room for error.

Changes

• Added new FeeComponents trait and implemented it for all fee components.
• Added new type and method to FeeHandler trait.
• Changed all actions in the fees request (fees::query::get_fees_for_transaction) to use helper functions with generic inputs.
• Refactored fee change tests to use helper function and macro, as opposed to generated tests. The aim of this is to make it more difficult to make manual mistakes in the future, while still making debugging of these tests easier.
• Refactored round trip state read/write tests.

Testing

Passing all tests

it doesn't look like there's a point to calling get_or_init_fees in this action or any of the ones below that are feeless, as they don't update fees_by_asset, which is the point of this function

[ethanoroshiba]

This was done so that the check would fail if the transaction would fail during execution (due to a given action not having fees). I think it may be worth it to keep this logic since it is used in mempool as well as check_and_execute and may catch a failure-bound transaction before it gets executed.
