fix(android/app): Update storage permissions for Android 12.0+

[darcywong00]

Fixes #10659 and follows the permission refactoring from #10904

Reference
https://developer.android.com/about/versions/13/behavior-changes-13#granular-media-permissions

This updates CheckPermissions to ask for the corresponding storage permissions needed to install local kmp files.

For Android API 30-32

• Manifest.permission.READ_EXTERNAL_STORAGE

For Android API 33+

• Manifest.permission.READ_MEDIA_IMAGES and
• Manifest.permissions.READ_MEDIA_VIDEO.
  (I tested without READ_MEDIA_AUDIO and it seemed to worked)

Note:
For these devices, the user needs to still manually grant these permissions from Android Settings before Keyman can access local .kmp files. This is documented in the updated help page: grant-storage-permission.md

Can we not request permission to access the files at the time it is needed? I've certainly seen that before. I would expect:

1. user selects file to open
2. Keyman pops a message saying it'll need file/video/photo access in order to open the file
3. User clicks OK, Keyman pops permission access request.
4. User clicks Allow, Keyman installs the package.

I think on older versions of Android, it used to prompt for the permission when the file is accessed. That seems to have changed over the years.
