  Add examples for reinterpret_cast and subview operators to show their behavior in relation to their input memref underlying memory and view (#135244)

While working on #134845 I was trying to understand the difference of
how the reinterpret_cast and subview operators see the input memref, but
it was not clear to me.

I did a couple of experiments in which I learned that the subview takes
into account the view of the input memref to create the view of the
output memref, while the reinterpret_cast just uses the underlying
memory of the input memref.

I thought it would help future readers to see these two experiements as
examples in the documentation to quickly figure out the difference
between these two operators.
