Removed Compression Gem DecompressorRegistrar streamer entry (#16959)
* Removed Compression Gem DecompressorRegistrar streamer entry
The DecompressionRegistrarEntry class replicates the logic of the
[FullFileDecompressor](https://github.com/o3de/o3de/blob/development/Code/Framework/AzCore/AzCore/IO/Streamer/FullFileDecompressor.h#L47-L56), but instead uses the AZ Task System instead of the
AZ Job System.
Because the DecompressionRegistrarEntry class hasn't been tested and is
unneeded for decompression of compressed files within a pak file, it
shouldn't be used.
