fix(node:zlib): expose stream instance shape

[andrewtdiz]

Summary

• expose zlib stream params and reset as function-valued instance properties
• track bytesWritten as a numeric property and publish it when queued zlib events drain
• add a granular parity fixture for method shape, bytesWritten timing, and absent bytesRead

Part of #793.
