Kernel: Remove the kmalloc_eternal heap :^)
This was a premature optimization from the early days of SerenityOS. The eternal heap was a simple bump pointer allocator over a static byte array. My original idea was to avoid heap fragmentation and improve data locality, but both ideas were rooted in cargo culting, not data. We would reserve 4 MiB at boot and only ended up using ~256 KiB, wasting the rest. This patch replaces all kmalloc_eternal() usage by regular kmalloc().
