    data: Make default indexed dirs configurable
    
    Add index_recursive_dirs and index_single_dirs meson options to allow
    passing which directories should be indexed by default. This makes it
    easier for sandboxed applications which use Tracker 3 inside the sandbox
    to change the directories they want indexed.
