[LoopInterchange] Constrain LI within supported loop nest depth (#118656)

This patch is an extension to #115128.

After profiling LLVM test-suite, I see a lot of loop nest of depth more
than `MaxLoopNestDepth` which is 10. Early exit for them would save
compile-time as it would avoid computing DependenceInfo and CacheCost.

Please see 'bound-max-depth' branch on compile-time-tracker.
