[17/36] xen/console: rename switch_serial_input() to console_find_owner()

Commit Message

From: Denis Mukhin <[e-mail]>

Updated the name to highlight the logic of selection the physical console
owner: existing code does not switch only serial console, it also switches
video console and debugging console (debug I/O port and console hypercall).
