fix/test(CL Fees): swap out given in fee growth tests; clean up swap tests

[p0mvn]

Closes: #XXX

What is the purpose of the change

Due to a merge conflict between #4021 and #4097, the fee growth validations were not added.

This PR adds the validations for the fee growth accumulator.

The changes from #4021 interfere with the assertions since they also relate to updating the fee growth accumulator. As a result, they were moved into a separate test fixture called TestSwapOutAmtGivenIn_TickUpdates to enable the expected fee growth validations in the original test.

Lastly, it cleans up the swap test suite. See changelog for details. This clean up is necessary for #4131 and is separated here for ease of review.

Brief Changelog

• move tick update tests into a separate fixture TestSwapOutAmtGivenIn_TickUpdates
• enable validation of the fee growth accumulator in TestCalcAndSwapOutAmtGivenIn
• do the first two steps for swap in given out in preparation for feat/test(CL Fees): Swap fees for in given out #4131
• group fee-specific tests in swapOutGivenInFeeCases global variable
  • this separation stems from the need to avoid running fee tests in tick updates or inverse tests
• group all test case fields in struct SwapTest and reuse it where applicable

Approved with the understanding that we are adding swapInGivenOutFeeCases post fee logic PR. Nicely done, very clean (the diff was super odd but reviewing the final file instead was much easier to grok)

[p0mvn]

merging since this is a simple test refactor
