feat(ext/flash): split upgradeHttp into two APIs (#15557)
This commit splits `Deno.upgradeHttp` into two different APIs, because
the same API is currently overloaded with two different functions. Flash
requests upgrade immediately, with no need to return a `Response`
object. Instead you have to manually write the response to the socket.
Hyper requests only upgrade once a `Response` object has been sent.

These two behaviours are now split into `Deno.upgradeHttp` and
`Deno.upgradeHttpRaw`. The latter is flash only. The former only
supports hyper requests at the moment, but can be updated to support
flash in the future.

Additionally this removes `void | Promise<void>` as valid return types
for the handler function. If one wants to use `Deno.upgradeHttpRaw`,
they will have to type cast the handler signature - the signature is
meant for the 99.99%, and should not be complicated for the 0.01% that
use `Deno.upgradeHttpRaw()`.
