Enable SQLite JNI for host Mac and Windows

SQLite JNI can compile and run on all host platforms, including Mac and
Windows. Also, make the Parcel-specific parts Linux only.

This will make SQLite available for all host runtimes, such as
LayoutLib, Ravenwood, and Robolectric.

This is a no-op change in terms of functionality.

Test: Robolectric SQLite tests on all host platforms
Flag: EXEMPT host-only no-op change
