x86/fpu: Rename save_xstate_sig() to copy_fpstate_to_sigframe()
Standardize the naming of save_xstate_sig() by renaming it to copy_fpstate_to_sigframe(): this tells us at a glance that the function copies an FPU fpstate to a signal frame. This naming also follows the naming of copy_fpregs_to_fpstate(). Don't put 'xstate' into the name: since this is a generic name, it's expected that the function is able to handle xstate frames as well, beyond legacy frames. xstate used to be the odd case in the x86 FPU code - now it's the common case.
