Revert "IVGCVSW-6359 Added support for Float16 (Half) to Execute Network"

This reverts commit 2d9956162dd002a41f7fb4fa6753195d33524c7f.

Reason for revert: After some discussion, this does technically implement Float16 support for ExecuteNetwork, but not in a way which matches most use cases and is likely to cause issues in the future. Reverting for now.
