This allows resources to be "streams" by implementing read/write/shutdown. These streams are implicit since their nature (read/write/duplex) isn't known until called, but we could easily add another method to explicitly tag resources as streams. `op_read/op_write/op_shutdown` are now builtin ops provided by `deno_core` Note: this current implementation is simple & straightforward but it results in an additional alloc per read/write call Closes #12556
