revset: don't cache abstractsmartset min/max invocations infinitely

There was a "leak", apparently introduced in ab66c1dee405. When running:

    hg = hglib.open('repo')
    while True:
        hg.log("max(branch('default'))")

all filteredset instances from branch() would be cached indefinitely by the
@util.cachefunc annotation on the max() implementation.

util.cachefunc seems dangerous as method decorator and is barely used elsewhere
in the code base. Instead, just open code caching by having the min/max
methods replace themselves with a plain lambda returning the result.
