feat(api-gateway): Meta - expose aliasMember for members in View (#8945)

Motivation for change:

While working on the new layer for MDX, I discovered that all members in views are defined as View's members. This leads to a problem: I am not able to separate them by cubes to align our model with Analysis Services.
