feat(ext/node): http2.connect() API (#19671)

This commit improves compatibility of "node:http2" module by polyfilling
"connect" method and "ClientHttp2Session" class. Basic operations like
streaming, header and trailer handling are working correctly. 
Refing/unrefing is still a TODO and "npm:grpc-js/grpc" is not yet working
correctly.
