[mubios] Implement serial input and BIOS console key handling
Implement UART receive, transmit timeouts, configuration and status reporting for INT 14h functions 00h-03h. Initialize the BDA serial timeout and expose the driver interfaces.
Translate terminal characters and CSI/SS3 escape sequences into BIOS keyboard events for INT 16h. Add blocking reads, non-consuming status queries, enhanced key reads and keyboard buffer insertion.
