Expose all profile flags for all CPUs when executing
query-cpu-model-expansion. This will allow callers to quickly determine
if a certain profile is implemented by a given CPU. This includes vendor
CPUs - the fact that they don't have profile user flags doesn't mean
that they don't implement the profile.

After this change it's possible to quickly determine if our stock CPUs
implement the existing rva22u64 profile. Here's a few examples:

 $ ./build/qemu-system-riscv64 -S -M virt -display none
-qmp tcp:localhost:1234,server,wait=off

 $ ./scripts/qmp/qmp-shell localhost:1234
Welcome to the QMP low-level shell!
Connected to QEMU 8.1.50

- As expected, the 'max' CPU implements the rva22u64 profile.

(QEMU) query-cpu-model-expansion type=full model={"name":"max"}
    {"return": {"model":
        {"name": "rv64", "props": {... "rva22u64": true, ...}}}}

- rv64 is missing "zba", "zbb", "zbs", "zkt" and "zfhmin":

query-cpu-model-expansion type=full model={"name":"rv64"}
    {"return": {"model":
        {"name": "rv64", "props": {... "rva22u64": false, ...}}}}

query-cpu-model-expansion type=full model={"name":"rv64",
    "props":{"zba":true,"zbb":true,"zbs":true,"zkt":true,"zfhmin":true}}
    {"return": {"model":
        {"name": "rv64", "props": {... "rva22u64": true, ...}}}}

We have no vendor CPUs that supports rva22u64 (veyron-v1 is the closest
- it is missing just 'zkt').

In short, aside from the 'max' CPU, we have no CPUs that supports
rva22u64 by default.
