Note: this is probably 25% broken, but it works right now as written, so I hope it all works.
- Added a new scheduler header file (scheduler.h) defining task structures, scheduling policies, and signal handling mechanisms.
- Integrated scheduling functions into the syscall interface, including SYS_GETPID, SYS_GETPPID, SYS_EXIT, SYS_SCHED_YIELD, SYS_NICE, SYS_KILL, SYS_SIGACTION, SYS_SIGPROCMASK, SYS_SCHED_GETSCHEDULER, and SYS_SCHED_SETSCHEDULER.
- Updated syscall handler to manage new scheduling-related syscalls and signal actions.

We have reorganized all the file directories that previously looked ugly as hell (cough cough arch/x86_64 cough)
Now it looks much cleaner

Finally we got usermode working again, It took awhile but we got it done. A few things we did in this commit:
- Simplified GDT entry initialization in gdt.c for kernel and user segments.
- Fixed TSS structure for task switching.
- Implemented cr2 handling in a page fault.
- Enhanced user stack setup in usermode.c to return the correct RSP.
- Improved syscall implementation in syscall.c, including new syscall numbers.
- Updated syscall entry to correctly handle context switching and argument passing.
- Refactored init.c to demonstrate file operations using syscalls.
- Added new syscalls for file operations in syscalls.h.
- Modified VFS to handle leading slashes in paths correctly.

- 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.

This implementation is incomplete, and doesn't work, but it will soon, to be determined, hopefully, uh, yknow.

- Implemented HDA driver in src/sound/hda.c, providing initialization, codec enumeration, and playback functionality.
- Defined HDA register offsets and structures in src/sound/hda.h.
- Added WAV file parsing and playback capabilities in src/sound/pcm.c, supporting both WAV and raw PCM formats.
- Created header file src/sound/pcm.h for PCM playback functions and WAV header structures.
- Integrated memory management for DMA buffers during audio playback.
Yes we played Charlie Charlie Kirky as the first sound on KirkOS
