[TTNN dialect] Matmul op implemented as DPS, but isn't DPS in lib

[svuckovicTT]

In TTNN Dialect, MatmulOp is implemented as DPS op. However, there's a single signature in lib for ttnn::matmul and it doesn't support a dest arg. Dialect needs to be fixed.

Lib:

struct MatmulOperation {
    static Tensor invoke(
        const Tensor& input_tensor_a,
        const Tensor& input_tensor_b,
        const bool transpose_a = false,
        const bool transpose_b = false,
        const std::optional<const MemoryConfig>& memory_config = std::nullopt,
        const std::optional<const DataType> dtype = std::nullopt,
        const std::optional<const MatmulProgramConfig>& program_config = std::nullopt,
        const std::optional<const std::string>& activation = std::nullopt,
        const std::optional<const DeviceComputeKernelConfig> compute_kernel_config = std::nullopt,
        const std::optional<const CoreGrid> core_grid = std::nullopt,
        const std::optional<const tt::tt_metal::Tile>& output_tile = std::nullopt);
};

tabledef:

def TTNN_MatmulOp : TTNN_NamedDPSOp<"matmul"> {
    let arguments = (ins AnyRankedTensor:$a,
                         AnyRankedTensor:$b,
                         AnyRankedTensor:$output);
    let results = (outs AnyRankedTensor:$result);

    let extraClassDeclaration = [{
      MutableOperandRange getDpsInitsMutable() { return getOutputMutable(); }
    }];

    let hasVerifier = 1;
}

Hey, @svuckovicTT we created an issue on the metal side regarding this a month ago:
tenstorrent/tt-metal#15038

They recently fixed this, and probably with the next metal uplift, we will have matuml DPS version.

That's awesome, confirmed it works for emitc mnist path, closing the issue.
