Move dashboard package into a common location where both Talos and talosctl can use it. Add support for overriding stdin, stdout, stderr and ctt in process runner. Create a dashboard service which runs the dashboard on /dev/tty2. Redirect kernel messages to tty1 and switch to tty2 after starting the dashboard on it. Related to siderolabs/talos#6841, siderolabs/talos#4791. Signed-off-by: Utku Ozdemir <utku.ozdemir@siderolabs.com>
