In the earlier http2 package migration (1d93bdce20, #17394) I had
removed Direct.Close's tracking of the connPool, thinking it wasn't
necessary.
Some tests (in another repo) are strict and like it to tear down the
world and wait, to check for leaked goroutines. And they caught this
letting some goroutines idle past Close, even if they'd eventually
close down on their own.
This restores the connPool accounting and the aggressife close.

A following change will split out the controlclient.NoiseClient type
out, away from the rest of the controlclient package which is
relatively dependency heavy.
A question was where to move it, and whether to make a new (a fifth!)
package in the ts2021 dependency chain.
@creachadair and I brainstormed and decided to merge
internal/noiseconn and controlclient.NoiseClient into one package,
with names ts2021.Conn and ts2021.Client.
For ease of reviewing the subsequent PR, this is the first step that
just renames the internal/noiseconn package to control/ts2021.
