Change renderbuffer width/height/sample types to GLsizei
This matches the types used by GL and stored in the state. setStorage
and setStorageMultisampled calls were using size_t instead with a number
of unnecessary casts in places which are now removed.

Distinguish MSRTT renderbuffers in the front-end
glRenderbufferStorageMultisampleEXT has different semantics from
glRenderbufferStorageMultisample. This change makes this
differentiation in the front-end and passes a flag to the backends.
This extension is currently only supported on Vulkan and D3D backends.
Support for the former will be done in a follow up. Support for the
latter is not planned.

Use angle::Result in front-end. (Part 1)
This covers most of the hot paths used in draw calls. Gives in the
order of a 5% reduction in draw call overhead.

Add gl::RenderbufferState shared state helper.
This shared state will be read-only visible in the RenderbufferImpl
class. It mirrors existing structs for Textures, Buffers, and other
classes. It allows the implementation class to have a read-only view
as to the current GL state of an object.
This will be useful to the Vulkan back-end, which would like to know
the current Renderbuffer state before having to redefine the storage.
If the current parameters match, it might not have to redefine the
storage at all.
The solution involves passing around the gl::RenderbufferState
through various factory methods.
Also name the Renderbuffer implementation pointer consistently and
make it use std::unique_ptr.

D3D11: Lazy robust resource init.
This patch moves the robust resource init logic to the GL front-end.
Instead of initializing texture resources immediately on creation in
D3D11, it defers the clear until before a draw call in some cases, or
skips the update if we can determine if a texture (or other resource)
has been fully initialized.
Currently lazy init is only implemented for Textures, Renderbuffers,
and Surfaces.
Various places where lazy resource init is triggered:
* Framebuffer operations (Draw, Blit, CopyTexImage, Clear, ReadPixels)
* Texture operations (SubImage, GenerateMipmap, CopyTexImage)
Some efficiency gains remain to be implemented, such as when a
SubImage call fills the entire object. Similarly for Blit, and a few
other operations. In these cases we can skip lazy init as an
optimization. Edge cases with EGLImage are mostly untested.

Pass Context to Framebuffer11 dirty callback.
This allows us to call StateManager11::invalidateRenderTarget from the
Framebuffer11::signal function, which will then trigger state refresh
on the next draw call.
This requires passing Context through a few more Renderbuffer methods,
and reorganizing the RenderTarget signalling so that it doesn't signal
dirty in the destructor. Instead they are signaled as they are
destroyed in the containing classes.
