feat(android)!: remove unnecessary permissions

Platforms affected

Android

Motivation and Context

This PR depends on #307

fixes #289

With the removal of Media Store queries, we do not need the READ/WRITE external storage permissions.

Description

Removed several methods for managing permissions as they were not necessary. KEPT camera permission handling for that fringe case where it is required if it is declared in the manifest.

Added GRANT WRITE flag to Video/Image intents, as that is necessary to give the third-party application write access to the specified directory (as provided by our File Provider). Audio must be handled differently.

The RECORD_SOUND_ACTION intent does not make use of the EXTRA_OUTPUT parameter therefore we cannot instruct the third-party application to write to a location of our choice. Instead they will always write to external storage. For consistency however, we will copy the file to the cache directory.

Testing

Ran Paramedic tests.
Manual tests with and without the CAMERA permission declared on API 28 & 29.
