Message: SERVER-81896 Move query fuzzers to their own variants

Implements the proposal that is documented and approved in WRITING-15587. This change will allow most Server engineer's patch builds to exclude query fuzzers, a common source of CI failure noise. There are a series of new variants to contain those query fuzzer tasks that were previously covered by the "required" alias. These new variants have display_name prefix "*|" so they can be easily found by humans on the evergreen UI (at the end of the list) and they have name suffix "-fuzzers" so they can be easily matched by a regex (eg., so we can create a patch alias to select all fuzzers).

The PR also extends the query fuzzer runtimes by about 4x.

The one reduction is coverage is the removal of aggregation_multiversion_fuzzer from the TSAN build, due to timeouts. I created SERVER-81896 to track re-enabling it.

There are also a few minor unrelated fixes in the evergreen.yml. I noticed some mismatches between the cron specs and their comments.
