x86/fpu/xstate: Align xstate components according to CPUID

CPUID function 0x0d, sub function (i, i > 1) returns in ecx[1] the
alignment requirement of component 'i' when the compacted format is used.

If ecx[1] is 0, component 'i' is located immediately following the preceding
component. If ecx[1] is 1, component 'i' is located on the next 64-byte
boundary following the preceding component.
