cachevfs: add a vfs dedicated to cache

Most of the cache content lives in '.hg/cache/'. Moreover they are computed
exclusively from data in the '.hg/store' directory. This creates issues with
the share extension as the '.hg/store' directory is shared but the '.hg/cache'
is not. On large repositories, this makes this prevent some usage of the share
extension inefficient as some caches can take minutes to be recomputed.

To improve the situation, we introduce a new 'cachevfs' that will be dedicated
to cache reading and writing. In the next patches of this series, we'll
migrate the 4 existing caches to it and update the share extension.
