[Relay][Frontend][TFLite] Add parser support for logical operators (#4642)

* [Relay][Frontend][TFLite] Add parser support for logical operators

* Add parser support for logical_and, logical_or
* Add boolean dtype as a valid tensor type
* BOOLEAN dtype is supported only from tf 1.15
  so logical ops work only in that and newer versions
* Logical_not is ommited since tflite can't convert it -->
  throws errors for addv2

* Add TFLite vesion check in tests for logical ops

* Check is added because of boolean dtype lack of support
