[Mac] Create and hold MtlTextures in SharedTextureMemoryMTL

Per validation constraints [1], the MtlTextures that TextureMTL creates
when initialized from SharedTextureMemory must match the properties of
the backing IOSurface that the SharedTextureMemoryMTL instance was
created with. This means that we can create the MtlTextures in
SharedTextureMemoryMTL on its creation and simply vend them out to
any TextureMTL objects that that SharedTextureMemoryMTL instance is
asked to create. This CL makes that change.
