[android] gpu logs functions (#3389)

Since Android is a pain when it comes to checking GPU logs in more depth, this is a better way to see what's going on, especially for testers...

This should be expanded to Mali, Xclipse, and Tensor in the future. Since I don't own any of these devices, it's up to developers with similar capabilities to add support for this system.

~~The GPU log sharing button should also be added in the future... For now, they are available in the same location as the traditional logs.~~ Added on 572810e022
