Optimize QuantumObjectType handling

[ytdHuang]

I find out that we have many codes like:

function f(A::QuantumObject{<:AbstractArray{T},OpType}) where {T,OpType<:QuantumObjectType} ... end 

where the funtion f basically supports all types of QuantumObject.

But this can be abbreviated as

function f(A::QuantumObject{<:AbstractArray{T}}) where {T} ... end

This can make the code more clear.
