feat(ext/node): Very basic node:http2 support (#19344)

This commit adds basic support for "node:http2" module. Not
all APIs have been yet implemented, but this change already
allows to use this module for some basic functions. 

The "grpc" package is still not working, but it's a good stepping
stone.
