MLIA-316 Specify cache arena size in the Vela memory profiles
When running the e2e test of Wav2Letter, the tensor allocation failed.
To resolve this, we changed the arena cache size to 2096768. This is
due to the requirement in Vela. We need to make it aware of the memory
limitation on the target we are deploying for.
