Subject: [PATCH 1/2] Replace libjs benchmarks with porffor

libjs benchmarks are no longer produced. Add porffor in its place,
unchecked by default like v8-jitless and sm-jitless.

Subject: [PATCH 2/2] Label porffor as AOT compiled on benchmarks page

Porffor compiles ahead of time, so its scores are not a like-for-like
comparison with the interpreters. Add an (AOT) label to its checkbox
and a note explaining the difference.
