arm64: use a common struct frame_record
Currently the signal handling code has its own struct frame_record,
the definition of struct pt_regs open-codes a frame record as an array,
and the kernel unwinder hard-codes frame record offsets.
Move to a common struct frame_record that can be used throughout the
kernel.
