6a5a63f051 analytics: Adding abstraction on tensor dims
Tensor can be row or col major, but it's also possible that the order by we need
to read the tensor with more than two dimension need to be described. The
reserved field in GstTensorDim is there for this purpose. If we need this we
can add  GST_TENSOR_DIM_ORDER_INDEXED, and follow an index defining order for
each dimension.

8169863f01 analytics: Make GstTensor more suitable for inline allocation
GstTensor contained two fields (data, dims) that were dynamicallay allocated. For
data it's for a GstBuffer and we have pool for efficient memory management. For
dims it's a small array to store the dimension of the tensor. The dims field
can be allocated inplace by moving it at the end of the structure. This will
allow a better memory management when GstTensor is stored in an analytics meta
which will take advantage of the _clear interface for re-use.

- New api to allocate and free GstTensor
To continue to support use-cases where GstTensor is not stored in an
analytics-meta we provide gst_tensor_alloc, gst_tensor_alloc_n and
gst_tensor_free that will facilitate memory management.
- Make GstTensor a boxed type

7c925eae61 analytics: Move batch to GstTensor
- batch_size is required to interpret the tensor depending on the tensor format
the batch are not necessarily memory plane therefore it's preferable to keep it
inside GstTensor.

43c7e524ce analytics: Decouple GstTensor from GstTensorMeta
- To support transporting tensor as GstMeta, Analytics-Meta and Media we need to
  decouple GstTensor from GstTensorMeta.
