Daniel Pouzzner 83e0e19e03 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.
