x86/fpu/xstate: Use fpstate for copy_uabi_to_xstate()
Prepare for dynamically enabled states per task. The function needs to retrieve the features and sizes which are valid in a fpstate context. Retrieve them from fpstate. Move the function declarations to the core header as they are not required anywhere else.
