x86/fpu: Factor out the FPU regset code into fpu/regset.c
So much of fpu/core.c is the regset code, but it just obscures the generic
FPU state machine logic. Factor out the regset code into fpu/regset.c, where
it can be read in isolation.
This affects one API: fpu__activate_stopped() has to be made available
from the core to fpu/regset.c.
No change in functionality.
