LOG: [AMDGPU] Correct pass dependencies for SILowerSGPRSpills (#109937)

Replace unused analysis (VirtRegMap) dependency with the used one (SlotIndexes)
Initializes `SlotIndexesWrapperPass` which is used by SILowerSGPRSpills to ensure that legacy pass manager finds it.
Removes the initialization for `VirtRegMapWrapperPass` since it is not requested in this pass.
