Fixes to support large hashing against HW without caching (in exclusive hardware access) Large hashing uses previous hash code with two descriptors and polling. Added wolfCrypt large hash tests for MD5, SHA and SHA256. Add missing MCAPI set size API's. Cleanup AES GCM large test. Changed MPLABX projects to default to PIC32MZ2048EFM144.
