Add an app list filtering feature

[tumatanquang]

First, this feature will merge / combine the two options Show System Apps and Show Offline Apps (in Settings → Behavior) into a single option.

On the main screen (app list screen), to the left of the settings icon (gear icon), add a filter icon to open app list filter options. The filter functions are as follows:

• App type (single choice):
  • All (both user + system apps / default)
  • User (apps only)
  • System (apps only)
• App filter (multiple choice / enabled all by default):
  • Hide offline apps
  • Hide uninstalled apps
  • Hide disabled apps
• Sort by (single choice):
  • App name (default)
  • Last update
  • Block status
• Sort order (single choice):
  • ASC (default)
  • DESC

This will be very helpful, making the app list much more organized.
