Subject: [PATCH 1/2] http2: add writableObjectMode and writableNeedDrain
 getters to Http2ServerResponse

Fixes nodejs/node#63000.

Http2ServerResponse was missing these two properties that exist on
OutgoingMessage and are documented as returning boolean values.

Added getters mirroring the pattern already used for writableFinished,
writableCorked, writableHighWaterMark, etc. in compat.js.

Subject: [PATCH 2/2] test-http2: add assertions for writableObjectMode and
 writableNeedDrain

These properties were added to Http2ServerResponse but had no assertions
in the existing test. Adding type checks to ensure they return booleans
and are accessible on the response object.
