Improve: SI Tune Feedback - Separate planes

[VitorSouzaLNLS]

Description

This PR updates the SI Tune Feedback system to handle the horizontal and vertical tune planes independently.

Previously, tune sources, PID gains, and maximum tune errors were shared between both planes. This change introduces independent configuration and feedback parameters for the X and Y planes, allowing each plane to use its own tune measurement source and PID controller settings.

Motivation

Separating the tune feedback configuration by plane provides independent control of the horizontal and vertical tunes. This is particularly useful when the two planes require different measurement sources, PID gains, or acceptable tune-error limits.

Changes

• Add independent tune source selection for the X and Y planes:
  • TuneXSrc-Sel
  • TuneYSrc-Sel
• Add independent maximum tune error limits:
  • MaxTuneXErr-SP/RB
  • MaxTuneYErr-SP/RB
• Add independent PID gains for each plane:
  • LoopPIDKpX/Y-SP/RB
  • LoopPIDKiX/Y-SP/RB
  • LoopPIDKdX/Y-SP/RB

@VitorSouzaLNLS , just a reminder: we already added a few PVs of the loop in the archiver appliance. When deploying this PR we should update PVs in the archiver...

PV names suggestion (to be discussed):

MaxTuneXErr-SP/RB -> TuneXMaxErr-SP/RB
MaxTuneYErr-SP/RB -> TuneYMaxErr-SP/RB
LoopPIDKpX/Y-SP/RB -> TuneX/YLoopPIDKp-SP/RB
LoopPIDKiX/Y-SP/RB -> TuneX/YLoopPIDKi-SP/RB
LoopPIDKdX/Y-SP/RB -> TuneX/YLoopPIDKd-SP/RB

To me this is a more natural keyword ordering (that, for exmaple, helps filtering PVs more naturally in the archive appliance)
