target/arm: Define syndrome function for MOPS exceptions
The FEAT_MOPS memory operations can raise a Memory Copy or Memory Set
exception if a copy or set instruction is executed when the CPU
register state is not correct for that instruction. Define the
usual syn_* function that constructs the syndrome register value
for these exceptions.
