target-arm: Add QOM subclasses for each ARM cpu implementation
Register subclasses for each ARM CPU implementation.
Let arm_cpu_list() enumerate CPU subclasses in alphabetical order,
except for special value "any".
Replace cpu_arm_find_by_name()'s string -> CPUID lookup by storing the
CPUID (aka MIDR, Main ID Register) value in the class.
