This patchset adds KUnit tests for allocator alignment
guarantees and improves kvec documentation.

Patch 1 adds KUnit tests for verifying alignment guarantees
in Rust kernel allocators. Tests cover Kmalloc, Vmalloc
and KVmalloc with both standard (128B) and large page-aligned
(8192B) allocations.

Patch 2 adds a practical usage example for KVec::as_slice
method, showing how to create KVec, push elements and convert
to a slice.

Both patches are co-developed with Geliang Tang. Based on [1].
Tested on x86_64 using KUnit.
