[camera] Resolution

[raymondr]

Prior to this change there was no way to control resolution of captured images on Android.
This created different behavior from iOS where resolutionPreset is honored.

Description

This modifies existing behavior where we were ignoring ResolutionPreset for image capture on Android. Users will capture different size images based on what they pass in. Before they always got
the largest image possible.

Thanks for the contribution!

This PR isn't trivial to review and we've begun refactoring the camera plugin as a whole, so I'm labeling it with "backlog". We will prioritize creating a temporary hotfix with this PR according to the issue's priority.

Doing a quick test on Android I find that taking a picture with ResolutionPreset.medium results in:
I/flutter (28622): File length is 120227
And taking a picture with ResoultionPreset.ultraHigh results in:
I/flutter (28622): File length is 1664740
Look like this PR is no longer needed

I'm going to close this since it seems to no longer be needed per the last comment.
