[tensor_filter] Support data layout for tensor

Data layout added for tensor_filter in GstTensorFilterProperties
Four data layouts are supported
- ANY - unknown does not matter
- NHWC - referred as channels last
- NCHW - referred as channels first
- none - doesnt fit with above options
These data layouts can be different for each other/tensor in other/tensors
Layout is taken input as a string, and then parsed for each tensor
This layout is stored in tensor_filter element itself to be used by its subplugins, and not passed to other elements in the pipeline
