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.
