refactor(android): remove query img usage

[breautek]

Will rebase after #906 & #902 is merged.

Platforms affected

Android

Motivation and Context

fixes #891
closes #725
closes #660

This code existed since the beginning of time and it does not appear to be relevant anymore.
Duplicates does not occur, even with using DATA_URL or creating modifications via scaling.

Additionally querying the media store on API 28 and lower requires broad READ_EXTERNAL_STORAGE permission. If we can remove numpics and the usage of queryImgDb then we can make READ/WRITE_EXTERNAL_STORAGE optional.

With this change, on API 29+ no permissions are necessary to use the plugin, except for CAMERA if it's declared (that workaround is still necessary).

On API 28 and lower, WRITE_EXTERNAL_PERMISSION is optional, but will be required if saveToPhotoAlbum option is enabled, which is a change I plan to make in another PR soon.

Additionally, the way it was detecting and attempting to remove duplicate images is dangerous, as media store objects can be inserted at any time by other applications. There is no guarantee that the image selected as the duplicate was actually the duplicate, or if there was a duplicate to begin with.

Description

Removed numpics and all code related to managing numpics

Testing

Manual test on API 24
Paramedic test passes
