xmpp: Replace jwchat with jsxc

- Update action to not configure jwchat anymore.

- Update action to not disable jwchat apache configuration.  Since the
  package is no longer installed, this could cause failures.

- Update action to no refer to jwchat in comments.

- Update jwchat-plinth Apache configuration to not include jwchat
  anymore.  Keep this file name for now instead of renaming it to
  jsxc-plinth as this would introduce additional complexity with little
  benefit.

- Install package libjs-jsxc instead of jwchat during xmpp setup.

- Create jsxc front page shortcut instead of for jwchat.

- Perform diagnostics on /http-bind/ URL needed for jwchat instead of
  /jwchat.

- Update links that launch XMPP web client.
