64-bit storage type is often used for certain settings like on-device or when dealing with models that are quality-sensitive. For example, a TFLite micro kernel supports 64-bit quantized types for 16x8 quantized operations.
Currently the Quant dialect allows up to 32 bit storage bits: [MaxStorageBits](https://github.com/llvm/llvm-project/blob/b903badd73a2467fdd4e363231f2bf9b0704b546/mlir/include/mlir/Dialect/Quant/QuantTypes.h#L55). Bump this limit up to 64.
