[shared_preferences] Shared preferences linux endorsement (#2864)

Endorses shared_preferences_linux.

Since shared_preferences_linux is pure Dart, this uses manual registration of the Linux implementation. It is similar to the solution used for path_provider, but improves on it by more narrowly tailoring the registration to cases where another registration hasn't already been done, and only checking the first time, thus avoiding the need for a variable to override it.

Updates shared_preferences_linux to depend on path_provider_linux rather than path_provider, to avoid adding unnecessary native plugin dependencies to other platforms.

Also adds a driver test for shared_preference_linux, which I missed in reviewing the initial shared_preferences_linux landing.
