[MLIR] Affine lowering support for Comparison Ops (#3872)

* Affine lowering support for
    1) GreaterEq
    2) LessEq
    3) Equal
    4) NotEqual

* - cast result op from i1 to i8 for comparision operators

* Addressed PR comments

* Style fix

* - style check
- use select instead of zero_extendi durinng CompOp lowering

* - fix style
- use createOneConstant and createZeroConstant helpers in select intrinsic

* Use NG_U8_TYPE_ID for BooleanType in ngraph dialect

* Diable CE and Softmax unit test in MLIR

* - LIT parser test for comparision ops

* - Affine dailect LIT tests for Comparision Ops

* Address PR feedback

* fix typo

* - use `cast` to deduce element Type
- add more strict type checking to LIT Test

* fix CHECK label's for comparision ops

* Use UInt8 in verification logic for CMP op's

* - use UInt8 for the resultOp verification Logic in CMP op
- fix unit test failures
