This new abstract type will be used to differentiate between static and
non-static CPUs in query-cpu-definitions.
All generic CPUs were changed to be of this type. Named CPUs are kept as
TYPE_RISCV_CPU and will still be considered static.
This is the output of query-cpu-definitions after this change for the
riscv64 target:
$ ./build/qemu-system-riscv64 -S -M virt -display none -qmp stdio
{"QMP": {"version": (...)}
{"execute": "qmp_capabilities", "arguments": {"enable": ["oob"]}}
{"return": {}}
{"execute": "query-cpu-definitions"}
{"return": [
{"name": "rv64", "typename": "rv64-riscv-cpu", "static": false, "deprecated": false},
{"name": "sifive-e51", "typename": "sifive-e51-riscv-cpu", "static": true, "deprecated": false},
{"name": "any", "typename": "any-riscv-cpu", "static": false, "deprecated": false},
{"name": "x-rv128", "typename": "x-rv128-riscv-cpu", "static": false, "deprecated": false},
{"name": "shakti-c", "typename": "shakti-c-riscv-cpu", "static": true, "deprecated": false},
{"name": "thead-c906", "typename": "thead-c906-riscv-cpu", "static": true, "deprecated": false},
{"name": "sifive-u54", "typename": "sifive-u54-riscv-cpu", "static": true, "deprecated": false}

This command is used by tooling like libvirt to retrieve a list of
supported CPUs. Each entry returns a CpuDefinitionInfo object that
contains more information about each CPU.
This initial support includes only the name of the CPU and its typename.
Here's what the command produces for the riscv64 target:
$ ./build/qemu-system-riscv64 -S -M virt -display none -qmp stdio
{"QMP": {"version": (...)}
{"execute": "qmp_capabilities", "arguments": {"enable": ["oob"]}}
{"return": {}}
{"execute": "query-cpu-definitions"}
{"return": [
{"name": "rv64", "typename": "rv64-riscv-cpu", "static": false, "deprecated": false},
{"name": "sifive-e51", "typename": "sifive-e51-riscv-cpu", "static": false, "deprecated": false},
{"name": "any", "typename": "any-riscv-cpu", "static": false, "deprecated": false},
{"name": "x-rv128", "typename": "x-rv128-riscv-cpu", "static": false, "deprecated": false},
{"name": "shakti-c", "typename": "shakti-c-riscv-cpu", "static": false, "deprecated": false},
{"name": "thead-c906", "typename": "thead-c906-riscv-cpu", "static": false, "deprecated": false},
{"name": "sifive-u54", "typename": "sifive-u54-riscv-cpu", "static": false, "deprecated": false}]
}
Next patch will introduce a way to tell whether a given CPU is static or
not.
