[PATCH qemu-server v6 11/21] cpu models: add 'builtin' flag to CPU model list endpoint

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

The /nodes/{node}/capabilities/qemu/cpu endpoint returns both QEMU CPU
models and PVE-builtin models (e.g., x86-64-v2) under the same 'custom:
false' category, making them indistinguishable for API consumers.

This is needed so the UI can filter out builtin models from the
reported-model dropdown when creating custom CPU models, since builtin
models are a PVE abstraction and not valid QEMU reported-model values.
