[libcpu/arm/cortex-m33]: Fix incorrect CPU architecture in GCC context switch

2025-11-02T08:23:31Z

The context_gcc.S file was incorrectly marked as cortex-m4 in both the doxygen comment and .cpu directive, while the IAR and KEIL versions correctly specify cortex-m33. This file uses ARMv8-M specific features (PSPLIM register, TrustZone support) that are not available in Cortex-M4. Changes: - Update doxygen group from cortex-m4 to cortex-m33 - Change .cpu directive from cortex-m4 to cortex-m33
