This reverts commit ee98d31c.

Reason for revert:
After the commit, SpatialLayerStructTraitTest.RoundTrip has been
consistently failing on msan.

I was able to reproduce the failure locally on my linux machine by
building and running media_unittests with these gn args:
is_component_build = false
is_debug = false
is_msan = true
msan_track_origins = 2
use_goma = true

Original change's description:
> media/video: Add SpatialLayer to VideoEncodeAccelerator::Config
> 
> This CL adds SpatialLayer to VideoEncodeAccelerator::Config so
> that a VEA client is able to configure a spatial layer encoding.
> The configuration is useful to configure temporal layer encoding
> too. Supporting temporal layer with vp9 hw encoder is a short
> term goal today.
