Daniel Henrique Barboza aeb2bc5950 qapi,risc-v: add query-cpu-model-expansion
This API is used to inspect the characteristics of a given CPU model. It
also allows users to validate a CPU model with a certain configuration,
e.g. if "-cpu X,a=true,b=false" is a valid setup for a given QEMU
binary. We'll start implementing the first part. The second requires
more changes in RISC-V CPU boot flow.

The implementation is inspired by the existing ARM
query-cpu-model-expansion impl in target/arm/arm-qmp-cmds.c. We'll
create a RISCVCPU object with the required model, fetch its existing
properties, add a couple of relevant boolean options (pmp and mmu) and
display it to users.

Here's an usage example:

./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
