Added uefi-library: wolfCrypt as UEFI driver

[danielinux]

• Adds a new wolfssl-examples/uefi-library module:
  - UEFI wolfCrypt boot-time protocol driver (libwolfcrypt.efi)
  - Standalone UEFI test application (test.efi) with KATs
  - Build/run targets for x86_64 and IA32, including no-hw/hw variants and QEMU flows
  • Includes runtime-safe API symbol load/relocation handling in the driver:
    • Detects whether protocol function pointers are already relocated
    • Attempting hw-first boot flow with graceful fallback (via startup.nsh script intercepting error code)

Pull request overview

This PR adds a new uefi-library module providing wolfCrypt as a UEFI boot-time protocol driver with hardware acceleration support, plus a companion uefi-static module for standalone UEFI applications. The implementation includes runtime symbol relocation, CPUID-based AES-NI detection with graceful fallback, and comprehensive cryptographic test coverage.

Changes:

• New UEFI protocol driver (libwolfcrypt.efi) exposing wolfCrypt APIs to UEFI applications
• Standalone test application (test.efi) with KATs for AES, SHA, RSA, ECC, ML-KEM, Dilithium, etc.
• Build system supporting x86_64/IA32, hardware/software variants, and QEMU integration
• Runtime symbol relocation guard and CPUID-based fallback mechanism via startup.nsh
