use eigen3 header instead of tf third_party/eigen3

[smuzaffar]

This change allows to pick up eigen3 header from our distribution of eigen instead of tensorflow/third_party/eigen3. This is needed for TF 2.16 but should work for old versions of TF too. This should be test with cms-sw/cmsdist#9360 and should be merged only after cms-sw/cmsdist#9360 is in IB.
