src: port Pipe to uv_pipe_bind2, uv_pipe_connect2

The introduction of the uv_pipe_bind2 and uv_pipe_connect2 methods in
libuv v1.46.0 changed the behaviour of uv_pipe_bind and uv_pipe_connect.
This broke the ability to connect to abstract domain sockets on linux.
This change ports PipeWrap to use the new uv_pipe_bind2 and
uv_pipe_connect2 methods to restore abstract domain socket support.

Fixes: #49656
Refs: libuv/libuv#4030
