[Frontend][Index] Add frontend option to skip indexing the stdlib (for test performance)

Browse Source 
Several tests related to indexing system modules were taking a considerable
amount of time (100+ seconds in the worst case) indexing the standard library.
This adds a frontend option to skip it and updates those tests to pass it.
