Fix incorrect name of decoderEnforceMaxRstFramesPerWindow property

Motivation:

apple#2728 introduces 2 properties to control Netty
`decoderEnforceMaxRstFramesPerWindow` settings:
`-Dio.servicetalk.http.netty.http2.decoderEnforceMaxRstFramesPerWindow.maxConsecutiveEmptyFrames=200`
`-Dio.servicetalk.http.netty.http2.decoderEnforceMaxRstFramesPerWindow.secondsPerWindow=30`

The first property was named incorrectly, it must be
`maxRstFramesPerWindow`.

Modifications:
- Add a new property:
`-Dio.servicetalk.http.netty.http2.decoderEnforceMaxRstFramesPerWindow.maxRstFramesPerWindow=200`;
- Use previous `maxConsecutiveEmptyFrames` value as a fallback for
backward compatibility;

Result:

Properties names are consistent with their names in Netty.
