Arguably the target_cpu_copy_regs function for each architecture is
misnamed as a number of the architectures also take the opportunity to
fill out the TaskState structure. This could arguably be factored out
into common code but that would require a wider audit of the
architectures. For now just replicate for riscv so we can correctly
report semihosting information for SYS_HEAPINFO.
