FRAME_ALLOCATOR global, make XunilFrameAllocator not hold Limine entries so it can be used without lifetimes, implement the process struct, add user heap by giving back heap_start from ELF and adding sbrk syscall, align ELF loading in userspace_stub, implement lots of libc functions in libxunil, remove x86_64 dependency from libxunil, add malloc and all required heap functions to libxunil and more syscall numbers, add a util file to libxunil, add build scripts for libxunil and doomgeneric
