MNT-16381 Transformers must validate the content stream mimetype

Browse Source 
- Addition of AbstractContentTransformer2.strictMimeTypeCheck(...) to check that the
     declared mimetype is the same as the Tika derived mimetype. Controlled by a new alfresco
     global property content.transformer.strict.mimetype.check (set to true by default).
   - Added the UnsupportedTransformationException to a number of transformation callers as
     they should have been handling it already.
   - Modified DifferrentMimeTypeTest to test the new strictMimeTypeCheck.
