all: enable disabled HTTP/2 tests

Update net/http to enable tests that pass with the latest update
to the vendored x/net.

Update a few tests:

Windows apparently doesn't guarantee that time.Since(time.Now())
is >=0, so to set a definitely-expired write deadline, use a time
firmly in the past rather than now.

Put a backoff loop on TestServerReadTimeout to avoid failures
when the timeout expires mid-TLS-handshake. (The TLS handshake
timeout is set to min(ReadTimeout, WriteTimeout, ReadHeaderTimeout);
there's no way to set a long TLS handshake timeout and a short
read timeout.)

Don't close the http.Server in TestServerWriteTimeout while the
handler may still be executing, since this can result in us
getting the wrong error.

Change the GOOS=js fake net implementation to properly return
ErrDeadlineExceeded when a read/write deadline is exceeded,
rather than EAGAIN.

For #49837
For #54136
