  perf dsos: When adding a dso into sorted dsos maintain the sort order (2024-07-07 22:26:29 -0700)

perf tools: Fix the performance issue for v6.10

These addresses the performance issues reported by Matt, Namhyung and
Linus.  Recently it changed processing comm string and DSO with sorted
arrays but it required to sort the array whenever it adds a new entry.
This caused a performance issue and fix is to enhance the sorting by
finding the insertion point in the sorted array and to shift righthand
side using memmove().
