[Fix] Tensor::setDataFormat handling of DataFormat::Default

Context

Fix aidge_backend_cpu#42

Implement back the behaviour of setDataFormat lost in !314 (merged) that transposing Tensor from/to DataFormat::Default does not lead to any data transposition. Only the dataFormat is changed.

Major modification

• upd: in DataFormat.hpp, change 'getDataFormatTranspose' name to 'getPermutationMapping'
• upd: use X-macro to keep DataFormat enum, string value, permutation with NCHW and description in synch
• add: number of dimensions information to X-macro
• upd: change 'DataFormatTransposeDict' array to 'permutationFromNCHW' and move it to a static function 'getPermutationFromNCHW'
• fix: do not transpose data in Tensor if current or new format is Default
