The PACBTI is an optional hardware security feature, the current implementation assumes that every SoC that has Armv8.1-M architecture extension, has the PACBTI hardware feature, which does not have to be the case. Hence, the `portHAS_PACBTI_FEATURE` is removed and the implementation is modified to rely on `configENABLE_PAC` and `configENABLE_BTI` macros that can either be set using CMake or FreeRTOSConfig.h header file. Enabling PAC and/or BTI on a port variant that doesn't have the PACBTI hardware feature would be caught by a `configASSERT` statement.

This directory tree contains the master copy of the FreeRTOS Armv8-M and Armv8.1-M ports. Do not use the files located here! These file are copied into separate FreeRTOS/Source/portable/[compiler]/ARM_CM[23|33|55|85]_NNN directories prior to each FreeRTOS release. If your Armv8-M/Armv8.1-M application uses TrustZone then use the files from the FreeRTOS/Source/portable/[compiler]/ARM_CM[23|33|55|85] directories. If your Armv8-M/Armv8.1-M application does not use TrustZone then use the files from the FreeRTOS/Source/portable/[compiler]/ARM_CM[23|33|55|85]_NTZ directories.
