Add virtio-rng driver and ProbeError::NoMatch for silent probe skipping
...
Add a virtio-rng entropy source driver that registers with the kernel
RNG subsystem. Introduce `ProbeError::NoMatch` so virtio drivers can
silently reject empty or wrong-type MMIO slots without spamming the boot
log with fatal errors or leaving devices stuck in the deferred queue.

Add BLAKE2s entropy pool with per-CPU ChaCha20 CSPRNG
...
Replace the single `SmallRng` with a proper two-layer RNG architecture:
- Global BLAKE2s-256 entropy pool that accumulates entropy and gates
seed extraction behind a 256-bit threshold.
- Per-CPU ChaCha20Rng instances that are lazily seeded from the pool on
first use and periodically reseed every 1 MB by XOR-ing a fresh BLAKE2
extract with 32 bytes of their own output.
The /dev/random chardev uses fill_random_bytes directly instead of
routing through the syscall layer.
