CtsVerifier: Write CA cert using MediaStore

Use the MediaStore API to write the CA cert needed for the CA tests
to the Download media collection.

Due to Scoped Storage changes in Android 11 it's no longer possible to
write the file directly to the /sdcard directory.

Change both CA cert notification tests to use the CA cert written to the
Download folder.

Test: Manual, install CtsVerifier and run "CA Cert Notification test".
