arm64/stacktrace: Export save_stack_trace_regs()
The ARM64 implements the save_stack_trace_regs function, but it is unusable for any diagnostic tooling compiled as a kernel module due the missing EXPORT_SYMBOL_GPL for the function. Export save_stack_trace_regs() to align with other architectures such as s390, openrisc, and powerpc. This is similar to the ARM64 export of save_stack_trace_tsk() added in git commit e27c7fa015d6.
