Add response_data event, CDP now captures the full body so that it can respond
to the Network.getResponseBody. This isn't memory efficient, but I don't see
another way to do it. At least this way, it's only capturing/storing every
response body when (a) CDP is used and (b) Network.enabled is called. That is,
as opposed to baking this into Http/Client.zig, which would force the memory
consumption for all use-cases.
There's arguably some optimizations we could make for XHR requests, which also
dupe/own the response. As of now, the response is dupe'd separately for CDP
and XHR.
With networking enabled, CDP listens to this event and emits a
`Network.loadingFinished` event. This is event is used by puppeteer to know that
details about the response (i.e. the body) can be queries.
Added dummy handling for the Network.getResponseBody message. Returns an
empty body. Needed because we emit the loadingFinished event which signals
to drivers that they can ask for the body.
Stream (to json) the Transfer as a request and response object in the various
network interception-related events (e.g. Network.responseReceived).
Add a page.request_intercepted boolean flag for CDP to signal the page that
requests have been intercepted, allowing Page.wait to prioritize intercept
handling (or, at least, not block it).
On client.request(req) we now immediately wrap the request into a Transfer. This
results in less copying of the Request object. It also makes the transfer.uri
available, so CDP no longer needs to std.Uri(request.url) anymore.
The main advantage is that it's easier to manage resources. There was a use-
after free before due to the sensitive nature of the tranfer's lifetime. There
were also corner cases where some resources might not be freed. This is
hopefully fixed with the lifetime of Transfer being extended.
go-rod appears to stop processing when it receives an error, such as
UnknownMethod. Added placeholder handlers for Network.setUserAgentOverride and
Page.stopLoading.
Setting a custom user agent is something still being discussed, so no-oping it
seems reasonable. And, due to the currently synchronous nature of the initial
page load, no-oping stopLoading also seems reasonable.

This is always run, but only the full webcomponents polyfill, it's very
small and isn't intrusive. This introduces a layer of indirection so that,
if the full polyfill is loaded, its monkeypatched constructor will be called
