Creates a static function on SkImage which converts the SkImage to a
GrBackendTexture. The texture is unowned by Skia, and must be deleted
by the caller. Allows for a no-copy / no-conversion fast path if the
provided image is unowned (unique()) and texture backed.

This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

GrExternalTextureData is an API for exporting the backend-specific
information about a texture in a type-safe way, and without pointing
into the GrTexture. The new detachBackendTexture API lets us release
ownership of a texture to the client.
SkCrossContextImageData is the public API that lets clients upload
textures on one thread/GrContext, then safely transfer ownership to
another thread and GrContext for rendering.
Only GL is implemented/supported right now. Vulkan support requires
that we add thread-safe memory pools, or otherwise transfer the
actual memory block containing the texture to the new context.

This also makes the required changed to src, tests, and tools. The few
public APIs modified by this change appear to be unused outside of Skia.
Removing these from the public API makes it easier to ensure users are
no longer using them.
This also updates GrGpu::wrapBackendXXX and the
::onWrapBackendXXX methods to clarify ownership.

Refactor GrGpuResource to contain two different pieces of state:
a) instance is budgeted or not budgeted
b) instance references wrapped backend objects or not
The "object lifecycle" was also attached to backend object
handles (ids), which made the code a bit unclear. Backend objects
would be associated with GrGpuResource::LifeCycle, even though
GrGpuResource::LifeCycle refers to the GpuResource, and individual
backend objects in one GpuResource might be governed with different
"lifecycle".
Mark the budgeted/not budgeted with SkBudgeted::kYes, SkBudgeted::kNo.
This was previously GrGpuResource::kCached_LifeCycle,
GrGpuResource::kUncached_LifeCycle.
Mark the "references wrapped object" with boolean. This was previously
GrGpuResource::kBorrowed_LifeCycle,
GrGpuResource::kAdopted_LifeCycle for GrGpuResource.
Associate the backend object ownership status with
GrBackendObjectOwnership for the backend object handles.
The resource type leaf constuctors, such has GrGLTexture or
GrGLTextureRenderTarget take "budgeted" parameter. This parameter
is passed to GrGpuResource::registerWithCache().
The resource type intermediary constructors, such as GrGLTexture
constructors for class GrGLTextureRenderTarget do not take "budgeted"
parameters, intermediary construtors do not call registerWithCache.
Removes the need for tagging GrGpuResource -derived subclass
constructors with "Derived" parameter.
Makes instances that wrap backend objects be registered with
a new function GrGpuResource::registerWithCacheWrapped().
Removes "budgeted" parameter from classes such as StencilAttahment, as
they are always cached and never wrap any external backend objects.
Removes the use of concept "external" from the member function names.
The API refers to the objects as "wrapped", so make all related
functions use the term consistently.
No change in functionality. Resources referencing wrapped objects are
always inserted to the cache with budget decision kNo.

Adds an entry point to GrContext to allow enumeration and tracing of GPU resources
via the newly added SkTraceMemoryDump.
Plan is for Chrome to call this on each of its GrContexts.
Dumps both the total size of GPU resources, as well as the total purgeable size.

*Use SkSurfaceProps to communicate DF text rather than a flag.
*Tell SkGpuDevice::Create whether RT comes from cache or not.

This code requires fewer macros to use it (just one), has less code in macro
definitions, and has simpler synchronization code (just atomic ints, no SkOnce,
no SkMutex, etc.)
A minor downside, we lose indentation and reverse-ordering in the final report:

Leaked SkFontMgr: 1
Leaked SkWeakRefCnt: 1
Leaked SkTypeface: 1
Leaked SkFlattenable: 3

This is motivated by wanting to land https://codereview.chromium.org/806473006/,

implementation of SkInstCnt uses them in function scope, which isn't safe.
