Subject: [PATCH] fix(kokoro): register streamStop on JSI host object

Kokoro::streamStop() exists in C++ but was never exposed via JSI in
ModelHostObject. This causes a runtime TypeError when
TextToSpeechModule.streamStop() tries to call this.nativeModule.streamStop(),
which is undefined.

Register it as a synchronousHostFunction, matching the pattern used for
SpeechToText's streamStop.
