Fix to #35212 - Query/Perf: Compile identifier lambdas passed to PopulateIncludeCollection rather than inline (#35213)
PopulateIncludeCollection (as well as couple other methods) take a number of delegate arguments. For scenarios with significant number of entities we see significant perf improvement when these delegates are compiled (like we used to do in EF8), rather than inlined. Fixes #35212
