crypto/tls: add Dialer.DialContext() to fix websocket client

Browse Source 
The latest golang.org/x/net websocket package v0.33.0 needs
Dialer.DailContext in crypto/tls.  This PR adds it.

Apps using golang.org/x/net are encouraged to use v0.33.0 to address:

CVE-2024-45338: Non-linear parsing of case-insensitive content in golang.org/x/net/html
CVE-2023-45288: net/http, x/net/http2: close connections when receiving too many headers

Tested with examples/net/websocket/dial.
