Pull request overview

Implements a new generic crypto abstraction in wolfHAL and wires in an STM32WB AES hardware-accelerator driver (plus test harness support and unit tests), enabling boards to expose crypto algorithms via an ops-table dispatch model.

Changes:

• Add generic whal_Crypto device type with ops-table dispatch (crypto.h/crypto.c) and document driver integration.
• Implement STM32WB AES accelerator driver supporting multiple AES modes and integrate it into the stm32wb55xx_nucleo board.
• Extend the test framework with WHAL_SKIP() and add crypto + endian tests (host + hardware harness).
