sparse: rework debugsparse's interface

hg debugsparse supports arguments like --include, similar to `hg
tracked --addinclude` or `hg log --include`. But in `hg debugsparse`,
the pattern is not an argument of the flag, instead the patterns are
the anonymous command line arguments.

Not only is this surprising, it makes it impossible to use --include
and --exclude in the same invocation, or --reset --exclude.

So I propose making debugsparse making --include, --exclude take an
argument, and rejecting anonymous command line arguments, as well as
allowing mixing several of these flags in one invocations.
