5186341c28 gstanalytics : Add tensor decoder element for yolo detection models 
Existing tensor decoder has been bifurcated into two seperate gst
element as:

`yoloodv5tensordecoder`: decodes tensors output(masks) from detection-only
models e.g yolov8s.onnx

`yolsegv8tensordecoder`: decoder tensors output(masks and logits) from
segementation models e.g FastSAM or yolov8s-seg

07920e7122 gst-analytics : Adapt and Rename fastsamtensordecoder to yolo based. 
YOLOv8 model have same tensor output format as FastSAM, so for better
generalization rename fastsamtensordecoder to yolotensordecoder. This
also requires code adaptation to support Yolo based model.

c2d83fabbd tensordecoders: fix wrong assumption in ultralightfacedetectortensordec 
- UltraLightFaceDetection was assmuming only one TensorMeta could be attach to
  buffer. We need to look at all TensorMeta attach to the buffer and check for
  the one it support.

2c3f2747d6 tensormeta: Check dimensions when retrieving tensor 
Modify the API to retrieve the tensor meta to check for the dimensions
as well.

Also fix an API mistake, the buffer whose dimensions should be checheck
is the one inside the GstTensor, not another buffer some outside.

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
