help: add topic about evolution, based on text from evolve extension

I've taken the text produced by `hg help evolution` when the evolve
extension is enabled and made that available by the same command with
just hg core. Changes I've made:

 * Added "(EXPERIMENTAL)" to the title. (That doesn't hide the topic
   from `hg help`, though.)

 * Replaced old-style `experimental.evolution=<names>` config by
   new-style `experimental.evolution.<name>=true`.

 * Replaces a "obsolete markers" by "obsolescence markers".

 * Removed most content from "Current feature status".

When the evolve extension is enabled, its help text takes precedence.

# A portable replacement for 'seq'
#
# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
