Kevin Lubick 6c78b8d3ae Revert "Move SkCamera.h to client_utils/android"
This reverts commit 8a54d86c78.

Reason for revert: Causing issues with Android CTS

Original change's description:
> Move SkCamera.h to client_utils/android
>
> Android still uses this
> https://developer.android.com/reference/android/graphics/Camera
> but no other client does.
>
> This adds a little adaption layer until Android is updated
> to use the View3D version.
>
> Move SkCamera.h to View3D.h. Change names to android::skia::CLASS
> instead of SkCLASS. (3DView is not a valid class name, so rename it to
> View3D.)
>
> Forward-declare SkMatrix. Do not override SkNoncopyable - just delete
> the copy constructor/operator=. Make fU and fV private in Patch3D.
>
> Make Sk3DView override View3D temporarily until Android can be switched
> over to the new class.
>
> (View3D from http://review.skia.org/291371)
>
> I made Patch3D and Camera3D be private classes as they are
> currently not used by Android and wanted to constrain the
> exposed API as much as possible.
