We normalize shorthand to longhand forms in check_expr(): enumeration
values with normalize_enum(), feature values with
normalize_features(), struct members, union branches and alternate
branches with normalize_members(). If conditions are an exception: we
normalize them in QAPISchemaEntity.check() and
QAPISchemaMember.__init(), with listify_cond(). The idea goes back to
commit 2cbc94376e "qapi: pass 'if' condition into QAPISchemaEntity
objects", v3.0.0.
Normalize in check_expr() instead, with new helper normalize_if().
