linuxkm/linuxkm_memory.c: require kernel 5.4+ for AESNI/AVX, and add fixup code in wc_linuxkm_fpu_state_assoc_unlikely() to cope with migrations. in save_vector_registers_x86(), on kernel < 5.17, check test_thread_flag(TIF_NEED_FPU_LOAD) as a workaround for irq_fpu_usable() missing check for in_kernel_fpu.

linuxkm: add WOLFSSL_COMMERCIAL_LICENSE alternative to kernel_fpu_begin()/kernel_fpu_end() in save_vector_registers_x86()/restore_vector_registers_x86(): allocate wc_linuxkm_fpu_savebufs as a buffer for os_xsave()/os_xrstor(), and use fpregs_lock()/fpregs_unlock() to inhibit softirqs/preemption.

linuxkm/linuxkm_memory.c: refactor SAVE/RESTORE_VECTOR_REGISTERS() to be per-process rather than per-CPU, and add migrate_disable/enable() to kernel_fpu_begin/end() because preempt_disable() is just a barrier on _PREEMPT_VOLUNTARY kernels;

linuxkm: in {save,restore}_vector_registers_x86(), check if vector register file has already been saved and invalidated, and if so, inhibit the kernel_fpu_{begin,end}() wrap and instead just use preempt_{disable,enable}() wraps.
