L2TauTagNNProducerAlpaka: do not call TF inference with empty grid

[mmusich]

PR description:

Fix for #45136.
Implemented in the same style as #44455 (originally from @valsdav).
When this input is passed to a TF model executed on a CPU without AVX512F AVX512_VNNI, the model is executed and returns an empty output without complaining. When AVX512F AVX512_VNNI instructions are present, the TF executor complains.

This PR avoids calling the TF inference if empty inputs are detected.

PR validation:

Run the HLT over all the error stream files from run-381543 and run-381544 following #45136 (comment).

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

Not a backport, but will be backported for data-taking purposes to CMSSW_14_0_X.
