target/riscv: add TYPE_RISCV_DYNAMIC_CPU
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:
