docs: document the privacy-filter.cpp backend in README and compatibility table
The privacy-filter.cpp backend (#10360) was registered in backend/index.yaml
and referenced from the PII feature docs, but was missing from the backend
catalog surfaces. Add it to the README "Backends built by us" table, the
compatibility table (Utilities & Other, CPU/CUDA 13/Vulkan), and the backend
type list in the backends feature doc.

Bring the Backend & Model Compatibility Table up to the full set of
backends published in backend/index.yaml (60+), organized by modality
with per-backend acceleration targets. Add an "Available Backends"
pointer and expand the backend-type list in the backends feature doc.
Update the README backend count to 60+ and add a "Backends built by us"
section listing the native C/C++/GGML engines maintained by the LocalAI
project (parakeet.cpp, voxtral.c, vibevoice.cpp, rf-detr.cpp,
locate-anything.cpp, depth-anything.cpp, LocalVQE, local-store).
