Added hardware interrupts

[ViktorPopp]

This PR implements hardware interrupt handling for InfinityOS, enabling the system to respond to hardware events asynchronously. Key changes include:

• Setting up the Interrupt Descriptor Table (IDT).
• Handling timer and keyboard interrupts.
• Basic interrupt service routines (ISRs) for essential hardware.

Known Issues:

• The implementation is functional but may require further optimization and testing for edge cases.

Testing:

• Verified timer and keyboard interrupts trigger correctly on AMD64 architecture.
• Confirmed the system does not crash during interrupt handling.

Next Steps:

• Expand ISR support for additional hardware devices.
• Improve interrupt prioritization and handling efficiency.
• Add more comprehensive testing for different hardware configuration
