rust: alloc: implement `Vmalloc` allocator Implement `Allocator` for `Vmalloc`, the kernel's virtually contiguous allocator, typically used for larger objects, (much) larger than page size. All memory allocations made with `Vmalloc` end up in `vrealloc()`.

rust: support large alignments in allocations Add support for large (> PAGE_SIZE) alignments in Rust allocators. All the preparations on the C side are already done, we just need to add bindings for <alloc>_node_align() functions and start using those.
