[Todo]: Optimize the `GhostAppOpenFile` of the `ApplicationManager`

Type of Todo-task.

• Potential problems check.
• Bugs fix.
• New features.

Description or reproduction method of potential problems and bugs, or description of new features(Please try one issue per question).

Some features on file path and access management.

When app uses function a to open a file and pass parameters, starting with ~ means to open the file with the relative path of app, and starting with / means to open the file with the absolute path. Invalid if it starts with another form.

Draft of some features

1. If the file path starts with ~, you can only access the files under the current app.
2. If the file path starts with /, you can access the files in the sdcard or root directory.
3. All apps with file access rights can read and write files in the sdcard directory.
4. All apps can read and write files in relative paths.
5. The root directory file can be read only when the app has the permission GhostAppPermissionsNativeApplication.
6. The root directory file can be read and written only when the app has the permission GhostAppPermissionsRoot.
7. Ordinary apps are only allowed to use absolute paths (with GhostAppPermissionsNormalUser).

Suggested solution.

None.
