refactor: set removal version for `Deno.RequestEvent`, `Deno.HttpConn` and `Deno.serveHttp()` (#22034)

This change:
1. Sets the removal version for `Deno.RequestEvent`, `Deno.HttpConn` and
`Deno.serveHttp()` for Deno v2. I thought it might be worth calling
`warnOnDeprecatedApi()` within `Deno.Request` and `Deno.HttpConn`
methods, but I thought just having it called within `Deno.serveHttp()`
might be sufficient.
2. Removes some possibly unneeded related benchmarks.

Towards #22021
