[TF FE] Switch off TF1 While support totally (#20774)

* [TF FE] Switch off TF1 While support totally

This is a total switch off due to GPU limitation

Signed-off-by: Kazantsev, Roman <roman.kazantsev@intel.com>

* Need additional fallback in Enter to avoid shapes problem

* Disable tests with While op
