Linux x86 SIMD: factor out unneeded kernel dependencies
Cleanup the kernel SIMD code by removing kernel dependencies.

 - Replace XSTATE_XSAVE with our own XSAVE implementation for all
   kernels not exporting kernel_fpu{begin,end}(), see #13059

 - Replace union fpregs_state by a uint8_t * buffer and get the size
   of the buffer from the hardware via the CPUID instruction

 - Replace kernels xgetbv() by our own implementation which was
   already there for userspace.
