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.
