[7.12] Reorganise packages and classes in searchable snapshots plugin (#70850)

Searchable snapshots classes have been spread over
multiple packages since the creation of the plugin's
project (mea culpa). With the addition of the shared
cache and other factorization of IndexInput's code
it becomes less obvious to navigate the plugin
codebase.

Backport of #70814 for 7.12
