* Bump up to MBed-TLS V3.5.1, make changes to Visual Studio Projects to account for this.
* Update MBedTLS Transport files to call psa_crypto_init() if the MBEDTLS_PSA_CRYPTO_C is set.
* Add WIN32_LEAN_AND_MEAN to the corePKCS11_MQTT_Mutual_Auth_Windows_Simulator demo. Add in a check for MBEDTLS_ERR_SSL_RECEIVED_NEW_SESSION_TICKET when making a TLS handshake.
* Change transport interface files from using void * to mbedtls_pk_context * instead per changes in the MbedTLS API.
* Changes to Fleet Provisioning Demo and Demo Setup to use ECDSA keys
* Remove non-32 bit configs from various VisualStudio Projects. Enforce all projects using WIN32_LEAN_AND_MEAN as well as winsock2.h
+ Optimise Cortex-M4F ports by inlining some critical section macros.
+ Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h.
+ Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked.
+ Add in new standard demo/test files TaskNotify.c/h and include the files in the simulator demos.
+ Update trace recorder code, and some demos to use the new version (more to do).
+ Introduce uxTaskPriorityGetFromISR().
+ Minor typo corrections.
+ Update MingW simulator demo to match the MSVC simulator demo.
