Aliaksandr Kalenik 2e9c8ab669 LibWeb: Register shutdown-on-close handler once in ReadableStreamPipeTo ...

Previously, we added a `reader.closed()` promise reaction during every
`ReadableStreamPipeTo::process()` call, which meant allocating a new
reaction objects for every processed chunk and retaining all of them
until the stream closed. The same issue existed for `writer.closed()`
inside `ReadableStreamPipeTo::read_chunk()`.

This change registers a single shutdown handler for both the reader and
the writer in the ReadableStreamPipeTo constructor.
