Subject: IVGCVSW-7174 Add Reshape support to TOSA Reference Backend

 * Spelling corrections and code refactors added to TosaCommon
 * TosaDTypeToString() implemented and used in TosaRef IsLayerSupported()
   instead of enum integer.
 * Using namespace armnn in TosaCommon OneToOneMappingTests and
   TosaReference TosaRefLayerSupportTests instead of armnn::ClassName.
 * Updated VerifyTosaAttribute() to also verify certain attributes
   from input and output shapes.
