Bug 1515004 - Move --with-android-sdk to moz.configure. r=nalexander Since ./mach bootstrap installs Android SDK into ~/.mozbuild, we should detect this location as default SDK install path. Also, --with-android-max-sdk and --with-android-min-sdk are still in android.m4 because confvars.sh sets MOZ_ANDROID_MIN_SDK_VERSION.

   * @note The behavior for window groups is managed by Windows.
   * - If an overlay icon is set for any window in a window group and another
   *   overlay icon is already applied to the corresponding taskbar button, that
   *   existing overlay is replaced.
   * - If null is passed in to replace the overlay currently being displayed,
   *   and if a previous overlay set for a different window in the group is
   *   still available, then that previous overlay is displayed.
