TOSA to TTIR: adding simple op conversion patterns

[sdjukicTT]

Added simple patterns that use the TosaToTTIRDefaultDPSOpConversionPattern. TOSA operations for which support is added:

• tosa.cast (mlir::tosa::CastOp);
• tosa.ceil (mlir::tosa::CeilOp);
• tosa.cos (mlir::tosa::CosOp);
• tosa.equal (mlir::tosa::EqualOp);
• tosa.exp (mlir::tosa::ExpOp);
• tosa.floor (mlir::tosa::FloorOp);
• tosa.greater (mlir::tosa::GreaterOp);
• tosa.logical_and (mlir::tosa::LogicalAndOp);
• tosa.logical_not (mlir::tosa::LogicalNotOp);
• tosa.logical_or (mlir::tosa::LogicalOrOp);
• tosa.logical_xor (mlir::tosa::LogicalXorOp).

Also added a test for each in test/ttmlir/Conversion/TosaToTTIR, as well as a test for:

• tosa.abs (mlir::tosa::AbsOp);
• tosa.add (mlir::tosa::AddOp);
• tosa.greater_equal (mlir::tosa::GreaterEqualOp).

Moved the test for tosa.mul (mlir::tosa::MulOp) in the test/ttmlir/Conversion/TosaToTTIR folder as well.
