promql: Organize legacy tests into appropriate files (#7989)

* Separate tests into:
** Aggregators
** Functions
** Operators
** Selectors
* Remove simple files and place tests into other files.
* Eliminate some of the _over_time tests since there are already plenty of
  edge cases present in the functions.test file.

Relates to #740
