console: Add loglevel prefix to interactive consoles

Browse Source 
In an attempt to make loglevels more visible (and therefore useful,
hopefully), this patch adds a prefix indicating the log level to every
line sent to an "interactive" console (such as a UART). If the code
contains a `printk(BIOS_DEBUG, "This is a debug message!\n"), it will
now show up as

  [DEBUG]  This is a debug message!

on the UART output.

"Stored" consoles (such as in CBMEM) will get a similar but more
space-efficient feature in a later CL.
