Colin Blundell a406959e50 Add transient attachments and initial Metal support ...

This CL does the following:

* Adds a "transient attachment" bit to texture usage. This bit
  specifies that the created texture will be used only during
  this render pass.
* Adds a TransientAttachments Feature that gates the usage of
  transient attachments.
* Adds support for transient attachments on Metal, where they're
  used to create textures as memoryless.
* Adds validation tests and an E2T test of the feature.

A followup CL will add support in Vulkan.
