Revert two CL's that added support for loading *.svgz resources
via the file scheme in the network service due to increased
memory use.

Original change's description:
> Chrome supports loading gzipped SVG files from the file scheme
> which was unsupported with the network service implementation.
>
> Note: The non-network service implementation of *.svgz loading
> is currently broken on Linux, but works on Windows and macOS.
> This change works on both platforms.

Also reverted a second CL containing a speculative fix:
> Fix memory performance regression in file:///*.svgz filter.
>
> A speculative fix for a 7%-19.2% regression of memory use. This
> change releases the ZLib buffers used for Gzip inflation - releasing
> the memory as soon as it is no longer needed instead of waiting for
> the URLResponseBodyConsumer instance to be deleted.
>
> This change also fixes an incorrect reset of |zlib_wrapper_|, which
> was calling release() instead of reset(), when zlib would fail to
> initialize. This was likely a latent bug and not the cause of
> the regression.
