+++ This bug was initially created as a clone of Bug #1418464 +++

I accidentally stole Bug 1418464 for just a piece of this work, so I'm cloning and updating that description:

It's nice that we have an Android Studio project that allow us to build geckoview_example and geckoview, but it would be nice if hitting the 'run' button would also bring in any changes to gecko itself. The workflow is basically:

1) Add a new method to GeckoView
2) Implement above method in Gecko using JS or native code
3) Write a test or new API in GeckoViewExample or other sibling project
4) Win

Since setting up a gecko build is such an involved process I think we could just punt on that. We'd probably just assume that 'mach build && mach package' works. I don't think we really want Studio to install a mozconfig, for instance. The instructions for getting this to work for developers would basically be 'mach bootstrap', set up mozconfig, then ensure 'mach configure' works.

This is tricky because there's a dependency chain:

mach stage-package (building the omnijar)
  depends on
mach build binaries (building libxul.so)
  depends on
generating JNI wrappers
  depends on
compiling Java

Now, in Bug 1444546 we moved the JNI wrapper generation into the
Gradle build, and we made a JNI wrapper generating task for each
variant.  That's a problem because there really is only one JNI
wrapper generation option -- whatever is invoked as part of |mach
build| -- and because the proliferation of tasks makes |mach
stage-package| depend on lots of _different_ compiling Java tasks
(duplicating tons of work and slowing builds down significantly).

This ticket narrows us down to two JNI wrapper generating tasks.  The
task names are complicated in order to not change too many things.

This is just the mechanics of dropping the flavor -- no real
consideration for whether it works yet.  These parts will all be
folded before landing.

Again, these will all be folded together.

This commit is the meat of the series.  (Remember, the series will all
land together; the parts are just for ease of reviewing.)

This moves the "with/without" Gecko binaries logic to depend on the
actual tasks invoked by Gradle.  If we are asked to `assemble`
GeckoView or Fennec (and we're not in the special circumstance of
|mach build|), then we are in the "withGeckoBinaries" flow:
- We invoke |mach build binaries| if COMPILE_ENVIRONMENT
- We invoke |make -C ... stage-package|
- We copy omni.ja and libs/ into place for the Android-Gradle AAR/APK packager

If we're not asked to `assemble` (or if we're under |mach build|, then
we don't do any of that.  We leave any omni.ja and libs/ in place, but
we don't require them.

If we get everything right, this somewhat transparently work the
moz.build system into the Gradle build system when it's required.  I'm
sure there will be issues, but we can start from this and work out
problems as they become clear.

Depends on D12802

There are some r+ patches which didn't land and no activity in this bug for 2 weeks.
