rust: alloc: implement `KVmalloc` allocator
commit 8362c2608ba1be635ffa22a256dfcfe51c6238cc upstream.
Implement `Allocator` for `KVmalloc`, an `Allocator` that tries to
allocate memory with `kmalloc` first and, on failure, falls back to
`vmalloc`.
All memory allocations made with `KVmalloc` end up in
`kvrealloc_noprof()`; all frees in `kvfree()`.
