This introduces the notion of FeatureLevel, currently consisting of
Core or Compatibility. Each AdapterBase is now constructed with the
FeatureLevel it supports.
When discovering PhysicalDevices, create an AdapterBase for each of
the FeaturLevels which that PhysicalDevice supports. For most of the
backends, this will mean Core and Compatibility, while OpenGL and
D3D11 support only Compatibility.

The problem is becasue a resource can not be set as input and
output at same time on device context. So we have to track used
slots and unset related slots before binding a group.
This CL also unset all affect slots when a render pass or compute
pass is end, so all related resources could be unref from the
device context.

Change AdapterBase from an alias to PhysicalDeviceBase to a thin
wrapper class holding a ref to a PhysicalDeviceBase. This way,
mutiple AdapterBases can point at the same PhysicalDeviceBase.
For now, InstanceBase wraps all PhysicalDeviceBases discovered by a
backend in a single AdapterBase. In the future, this relationship will
become many-to-one.
Since Devices now maintain a ref on the AdapterBase wrapper (in order to
query toggles, etc), PhysicalDeviceBase::CreateDeviceImpl() now takes
the AdapterBase as an argument, so that the PhysicalDeviceBase knows
which AdapterBase to vend a Device for.
Note that the Toggles also still remain on the PhysicalDeviceBase, to
be moved up to the AdapterBase in a future change.
