sys: Implement LAPIC and IOAPIC support, add PS/2 keyboard driver

Browse Source

- Added LAPIC implementation in `apic.c` and `apic.h`, including initialization and basic operations.
- Introduced IOAPIC (I/O Advanced Programmable Interrupt Controller) support in `ioapic.c` and `ioapic.h`, parsing the ACPI MADT to locate IOAPICs and manage redirection entries.
- Implemented PS/2 keyboard driver in `ps2.c` and `ps2.h`, handling keyboard interrupts and translating scancodes to ASCII.
- Attempted to make usermode work again (it failed, coming soon)
- Cleaned up comments in `time.c` and `render.c` for clarity.
