Fixing bugs in nGraph reference implementation of Interpolate-4 (#2204)

* Now coordinate_transformation_mode used for all axes in the 'nearest' mode.

* Temporarily added tests for Interpolate-4 evaluate().

* Deleted temporarily added tests.

* Fixed documentation for the 'nearest' mode.

* Small fixes.

* Disabled Interpolate-4 layer tests for CPU.

* Disabled some Interpolate-4 CPU tests.

* do not change index table when execute each time

* layout check added

* interpolate for no batch size even scale is 1

* coordinate transformation with div scale, not multiple 1/scale, for higher accuracy

* disable tests temporal

* test modification
