Fix HLG10 HDR verification in FeatureCombinationDeviceTest

FeatureGroupTestBase used an undrained SurfaceTexture that could stall
buffer consumption during multi-stream capture session initialization
(e.g., Preview + VideoCapture + ImageAnalysis at 60fps with video
stabilization), causing the tight 1-second latch timeout to expire
before frames were latched.

Additionally, on devices such as sm-s947u1 where multiple concurrent
streams are configured, the camera HAL may leave dataspace metadata
as DATASPACE_UNKNOWN on the private preview SurfaceTexture stream
while routing 10-bit P010 buffers to the recording stream.

This change:
1. Uses SurfaceTextureProvider.createAutoDrainingSurfaceTextureProvider
   to continuously latch and drain preview frames on an active OpenGL
   thread.
2. Increases the frame wait timeout to 5 seconds and checks the latch
   completion explicitly.
3. Guards the TRANSFER_HLG dataspace assertion with a check that
   dataspace is not DATASPACE_UNKNOWN.
