feat: Add initial Supervisor Mode Trap Handler
Implement the initial mechanism for handling traps and exceptions in Supervisor Mode.
Set up the stvec Control and Status Register (CSR) to direct all S-Mode Traps (Interrupts and Exceptions) to a unified assembly entry point.
Implemented assembly code for saving and restoring the Trap Context (register state).
Provides the foundational framework necessary for future Timer Interrupts and System Calls.
