Revert of Add support for Java nano protocol buffers for Android. (patchset #4 id:60001 of https://codereview.chromium.org/511283003/)

Reason for revert:
Breaks some workflows and also should get new quota.

Original issue's description:
> Add support for Java nano protocol buffers for Android.
>
> This CL adds a new dependency on the protocol buffer compiler
> from the android source tree, since this compiler supports
> generating Java files using the nano runtime.
>
> The initial version of this dependency is 2.2.0a, but checked
> out as what the Android 4.4.4 Release 2.0.1 tag points to.
>
> This CL adds a new protoc binary (for compiling protos) that supports
> this, and also adds a Java library with the runtime.
>
> To simplify use of this, it also updates build/protoc_java.gypi to
> support generating nano protos by specifying an optional
> proto_runtime argument. The argument defaults to 'lite' which does
> the same thing as before this change, and setting it to 'nano'
> generates the new style Java files.
>
> The plan is to quickly deprecate the 'lite' runtime for Java, since
> it is too big and uses too many methods.
