Refactor and implement interrupt handling and PIT driver

- Refactored CPU context structure for better readability.
- Enhanced corpse and exception structures with clearer formatting.
- Improved frame structure for consistency.
- Added interrupt flag operations for enabling and disabling interrupts.
- Implemented IDT (Interrupt Descriptor Table) operations including loading and setting gates.
- Created PIC (Programmable Interrupt Controller) initialization and masking functions.
- Developed PIT (Programmable Interval Timer) driver with initialization and handler functions.
- Established common interrupt handler structure and exception handling stubs.
- Added hardware IRQ handling for IRQs 0-15.
- Introduced IDT entry and gate descriptor types for better organization.
- Ensured proper handling of interrupt and exception vectors.
