Suppose we have an alias 'immutable()' = '::immutable_heads()', user can
express (visible) mutable set as '~immutable()'. 'immutable_heads()..' can
terminate early, but a generic difference 'all() & ~immutable()' can't.
Suppose the generation value is usually small, it should be faster to do
bounded range look up first 'y-', then walk ancestors with the unwanted set
'y-..x'.
In my linux stable mirror, this makes the default log revset evaluation super
fast. immutable_heads(), if configured properly, includes many historical
branch heads which are also the visible heads.

Summary: In preparation for unifying all workspace dependencies across all
crates, let's go ahead and move the jj-cli crate into its own new directory.
This will also be a nicer and more uniform layout as we add new `jj-*` crates.
