Enable more parts of AttributeLayoutTest because:
- partial Vulkan support for vertex data in client memory has landed
- we can work around bugs which prevented some parts from working
- we have more fine-grained control over which parts to run

Avoid glBufferSubData to work around ANGLE bug 2374.

Let subclasses decide about skipping test cases.  For example on Vulkan
indexed draw with vertex data in client memory is not supported yet.

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.
