They are now more readable. I'll do another pass and start
separating integration testing from unit testing.
I think we need to have some always on integration testing
for netxlite that runs on macOS, linux, and windows.
See https://github.com/ooni/probe/issues/1591
This basically adapts already existing code inside websteps to
instead be into the netxlite package, where it belongs.
In the process, abstract the TLSDialer but keep a reference to the
previous name to avoid refactoring existing code (just for now).
While there, notice that the right name is CloseIdleConnections (i.e.,
plural not singular) and change the name.
While there, since we abstracted TLSDialer to be an interface, create
suitable factories for making a TLSDialer type from a Dialer and a
TLSHandshaker.
See https://github.com/ooni/probe/issues/1591
We are proceeding with this plan of every major type being able to
close idle connections, which will simplify making DNS resolvers.
See https://github.com/ooni/probe/issues/1591.
Like we did before for the resolver, a dialer should propagate the
request to close idle connections to underlying types.

## Description
This PR continues the refactoring of `netx` under the following principles:
1. do not break the rest of the tree and do not engage in extensive tree-wide refactoring yet
2. move under `netxlite` clearly related subpackages (e.g., `iox`, `netxmocks`)
3. move into `internal/netxlite/internal` stuff that is clearly private of `netxlite`
4. hide implementation details in `netxlite` pending new factories
5. refactor `tls` code in `netxlite` to clearly separate `crypto/tls` code from `utls` code
After each commit, I run `go test -short -race ./...` locally. Each individual commit explains what it does. I will squash, but this operation will preserve the original commit titles, so this will give further insight on each step.

* refactor: rename netxmocks -> netxlite/mocks

* refactor(iox): move MockableReader to netxlite/mocks
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): generator is an implementation detail
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): separate tls and utls code
See https://github.com/ooni/probe/issues/1591
* refactor(netxlite): hide most types but keep old names as legacy
With this change we avoid breaking the rest of the tree, but we start
hiding some implementation details a bit. Factories will follow.
