Revert "Use mojo_base.mojom.ReadOnlySharedMemoryRegion in device sensors."

This reverts commit 076ef25936e7142c67e21d9295dd92a139164e71.

Reason for revert: prereq for reverting https://crrev.com/c/3625893

Original change's description:
> Use mojo_base.mojom.ReadOnlySharedMemoryRegion in device sensors.
>
> Unfortunately, the CL largely relies on using static_cast<const T*>
> instead of the safer GetMemoryAs<T> helper, since GetMemoryAs<T> requires
> that device::SensorReadingSharedBuffer is trivially copyable.
