rust: alloc: implement `Vmalloc` allocator
commit 61c004781d6b928443052e7a6cf84b35d4f61401 upstream.
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()`.
