This removes the TARGET_* conditions from all the CPU commands
that are conceptually target independent. Top level stubs are
provided to cope with targets which do not currently implement
all of the commands.

+# The data returned by this command may be affected by:
+#
+# * QEMU version: CPU models may look different depending on the QEMU
+# version. (Except for CPU models reported as "static" in
+# query-cpu-definitions.)
+# * machine-type: CPU model may look different depending on the
+# machine-type. (Except for CPU models reported as "static" in
+# query-cpu-definitions.)
+# * machine options (including accelerator): in some architectures,
+# CPU models may look different depending on machine and accelerator
+# options. (Except for CPU models reported as "static" in
+# query-cpu-definitions.)
+# * "-cpu" arguments and global properties: arguments to the -cpu
+# option and global properties may affect expansion of CPU models.
+# Using query-cpu-model-expansion while using these is not advised.
+#
+# Some architectures may not support all expansion types. s390x
+# supports "full" and "static". Arm only supports "full".
+#
+# @model: description of the CPU model to expand
+#
+# @type: expansion type, specifying how to expand the CPU model
+#
+# Returns: a CpuModelExpansionInfo describing the expanded CPU model
+#
+# Errors:
+# - if expanding CPU models is not supported
+# - if the model cannot be expanded
+# - if the model contains an unknown CPU definition name, unknown
+# properties or properties with a wrong type
+# - if an expansion type is not supported

+# accelerator options. A static model is always migration-safe.

+# removed in in some future version of QEMU according to the QEMU
+# deprecation policy. (since 5.2)
+#
+# @unavailable-features is a list of QOM property names that represent
+# CPU model attributes that prevent the CPU from running. If the QOM
+# property is read-only, that means there's no known way to make the
+# CPU model run in the current host. Implementations that choose not
+# to provide specific information return the property name "type". If
+# the property is read-write, it means that it MAY be possible to run
+# the CPU model in the current host if that property is changed.
+# Management software can use it as hints to suggest or choose an
+# alternative for the user, or just to generate meaningful error
+# messages explaining why the CPU model can't be used. If
+# @unavailable-features is an empty list, the CPU model is runnable
+# using the current host and machine-type. If @unavailable-features
