linuxkm feature additions:
...
add build-time support for module signing using native Linux facility;
add support for alternative licenses using WOLFSSL_LICENSE macro;
improve load-time kernel log messages;
add support for sp-math-all asm/AVX2 acceleration;
add error-checking and return in SAVE_VECTOR_REGISTERS();
implement support for x86 accelerated crypto from interrupt handlers, gated on WOLFSSL_LINUXKM_SIMD_X86_IRQ_ALLOWED:
* wolfcrypt_irq_fpu_states
* am_in_hard_interrupt_handler()
* allocate_wolfcrypt_irq_fpu_states()
* free_wolfcrypt_irq_fpu_states()
* save_vector_registers_x86()
* restore_vector_registers_x86()
add WOLFSSL_LINUXKM_SIMD, WOLFSSL_LINUXKM_SIMD_X86, and WOLFSSL_LINUXKM_SIMD_ARM macros for more readable gating.

Linux kernel module: add an explicit -ffreestanding to CFLAGS in linuxkm/Makefile, and in wc_port.h ifdef WOLFSSL_LINUXKM, ignore -Wtype-limits in Linux kernel header files (needed for kernel v5.13), and suppress inclusion of stdint-gcc.h.

add "module", "modules_install", and "clean_module" rules to BUILD_LINUXKM section of Makefile.am, and add working install rule to linuxkm/Makefile, so that "make module" and "make modules_install" now work when --enable-linuxkm; fix "make dist" logic in Makefile.am and scripts/include.am to be unaffected by --enable-linuxkm; don't build wolfcrypt/benchmark or testwolfcrypt when --enable-linuxkm and --enable-crypttests.

linuxkm: configure.ac more incompatible options: --enable-fastmath, --enable-iopool, and --enable-fips; linuxkm/Makefile: reduce -Wframe-larger-than from 65536 to kernel-compatible 5000; wolfssl/wolfcrypt/settings.h: unset HAVE_THREAD_LS when WOLFSSL_LINUXKM; wolfssl/wolfcrypt/types.h: when NO_INLINE and __GNUC__, #define WC_INLINE __attribute__((unused)) rather than to nothing to avoid -Wunused-function warnings; wolfssl/wolfcrypt/wc_port.h: #undef noinline after Linux kernel header includes (another macro conflict).
