On D3D12 and Vulkan start first frame capture on API init. Closes #1195

* On GL/D3D11 we delay the start of the 'first frame' until a swapchain has been
  created for D3D11, or an attribs-created context has been created for GL. This
  makes it more useful and doesn't fire when creating devices/contexts for
  enumeration or trampolining.
* On Vulkan/D3D12 the first device that's created is useful, so we can start
  capturing immediately once it's available.
