revsetbenchmark: add more example for roots usages

We test the `roots` revset in setting similar to our test for `heads`.

Note that the algorithm used for roots can give result without consuming the
full input set. This provides a significant speedup when testing or accessing
a single value. We can't just replace it with simple, full algorithm like we
did for `heads`. See performance number below:

0) roots((tip~100::) - (tip~100::tip))
1) roots((0::) - (0::tip))
2) roots(tip~100:)
3) roots(:42)
4) roots(not public())
5) roots((0:tip)::)
6) roots(0::tip)
7) 42:68 and roots(42:tip)
8) roots(0:tip)
9) roots((:42) + (tip~42:))
10) roots(all())
11) roots(-10000:-1)
12) (-5000:-1000) and roots(-10000:-1)
13) roots(matching(tip, "author"))
14) roots(matching(tip, "author")) and -10000:-1
15) (-10000:-1) and roots(matching(tip, "author"))

 # All revsets ever used with revsetbenchmarks.py script
 #
 # The goal of this file is to gather all revsets ever used for benchmarking
 # revset's performance. It should be used to gather revsets that test a
 # specific usecase or a specific implementation of revset predicates.
 # If you are working on the smartset implementation itself, check
 # 'base-revsets.txt'.
 #
 # Please update this file with any revsets you use for benchmarking a change so
 # that future contributors can easily find and retest it when doing further
 # modification. Feel free to highlight interesting variants if needed.
 
 
 ## Revset from this section are all extracted from changelog when this file was
 # created. Feel free to dig and improve documentation.
