fix(android): refactor font copy / support android gradle plugin 4.1+

- react-native JS bundle doesn't copy per-release target
- react-native JS bundle adds the copy task as dependent very carefully now!
- I added some metadata for the task, a "group" and "description"
- Fixed formatting, 4-space indents was predominant, I went with that everywhere

this is based heavily off the react-native JS bundle copy task
this was developed in collaboration with @gulshan183

Fixes oblador#1265
