When websocket disconnects during `browserType.connect()` call, the
error looks like this now:
```
browserType.connect: Custom error message received over WebSocket
```
Previously, it was a generic error:
```
browserType.connect: Target page, context or browser has been closed
```
Closes https://github.com/microsoft/playwright/issues/23566
n.b., while that issue describes a fairly specific "use case", this
logging is simple and generic. It seems very plausible that it can help
diagnose all sorts of issues.

`x-playwright-debug-log: value` headers are printed to `pw:browser`
debug log.
`x-playwright-attachment: name=value` headers are attached to each test.
Fixes#21619.
This wraps happy eyeballs in two places, the place where we make the
JSON request to Chromium and the actual CDP WebSocket request.
It required changes inside our happy eyeballs implementation since the
[websocket library does not
set](https://github.com/websockets/ws/blob/master/lib/websocket.js#L714)
the `clientRequestOptions.hostname` field, it just sets the `host` field
where we then fall back to when its not set.
This test would pass before Node.js 18 and fail after Node.js 18 without
my changes.

This patch implements a new mode of network tethering for Playwright
server & its clients.
With this patch:
- playwright server could be launched with the
`--browser-proxy-mode=tether` flag to engage in the new mode
- a new type of client, "Network Tethering Client" can connect to the
server to provide network traffic to the browsers
- all clients that connect to the server with the `x-playwright-proxy:
*` header will get traffic from the "Network Tethering Client"
This patch also adds an environment variable
`PW_OWNED_BY_TETHER_CLIENT`. With this env, playwright server will
auto-close when the network tethering client disconnects. It will also
auto-close if the network client does not connect to the server in the
first 10 seconds of the server existence. This way we can ensure that
`npx playwright docker start` blocks terminal & controls the lifetime of
the started container.
