Go Heap Profiles to Gain Complete Memory View via New memory_space Sample Type

A Go proposal (#79179) provisionally accepted to add a memory_space sample type to heap/alloc profiles, providing a full memory hierarchy from RSS down to live/dead heap, stacks, runtime, and non-Go memory, solving the long-standing gap where heap profiles show only about 50% of actual RSS.
