[google_maps_flutter + platform] Tweaks to enable a web implementatio…

…n. (flutter#2903)

This change tweaks slightly the core maps plugin and the platform interface package to make the web implementation possible.

The most important changes are two:

* The core plugin now passes a constant identifier to the buildView platform call, so the web version can cache effectively the contents of the platform view, so it doesn't repaint. This might go away once Scenelets for web come online.
* The platform interface now encodes the (optional) width and height of custom Icons for Markers, so the web can render High DPI assets at the correct size.

The rest are some examples to the 'example' app so it can be run on web.

[shared_preferences] Shared preferences linux endorsement (flutter#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.
