COMPMID-3539: Ignore align_corners for scaled size of 1
Scale kernels failed to validate when align_corners is true
for scaled output size 1. Change this behavior to ignoring
align_corners value to be aligned with expected behavior of
higher-level frameworks.
Also the minimum output size generated by the fixture for
Scale kernels is changed to 1.
