fix(store): remove Android and iOS plugins, closes #1256 (#1695)

The Android and iOS support introduced on #1011 is not really supported - the Tauri path API correctly resolves the cache directory on mobile, and we can access those directly using Rust code.

This is a breaking change because we no longer uses the same directory to store the files - app_cache_dir returns a different location
