Adjust Order of Tightening Timings

[HarrySIsNotAvailable]

My aim in this PR is to change the order of tightening specific timings that depend on others first.

1. Moved tuning tCWL before tWTRS/L (which involves changing tWRRD) because Eden from the Overclocking Discord recommends that tCWL should be tuned before tWRRD and that tuning tCWL after will complicate things.

2. Moved tuning tWR and tRTP after tCWL because of this rule: tWR = tWRPRE - tCWL - 4. Hence, I have grouped tuning tWR and tRTP with tCWL, tWTRS/L which is now all in step 3 in the correct order. This also talks about tRTP which wasn't in the table at all before this PR (maybe it was a while ago?).

• The extreme preset is not the minimum floor in this case. tRTP can go as low as 5 (6 with Gear Down Mode on), while tWTRS/L can go as low as 1/6. Some boards are fine doing tCWL as low as tCL - 6. Keep in mind that this will increase the load on your memory controller.
