Android: setting out for a target breaks the build if there is 2 or more variants

[oldergod]

Wire will generate a task per variant but they'll end up having the same output location which will cause troubles.
We should either throw if we detect this scenario, and/or allow the consumer to set an output dir per variant

Would it make sense to generate a single task that is then used by all Android variants? It simplifies the build a lot and I think this is the default that most builds want?

For users that really want different .proto for debug vs release variants, there could be a way to generate multiple schemas and "wire" (no pun intended :)) to different variants.

By the way, the issue isn't up to date.
Each task would now emit into its own directory as shown in this sample https://github.com/square/wire/tree/master/samples/android-app-variants-sample

Were we to generate everything at the same location, one could still customize the schema handlers' block with the out field.
