Add generic.total_physical_bytes property to MallocExtension
Original CL:
- https://codereview.chromium.org/1410353005
Add generic.total_physical_bytes property to MallocExtension
The actual physical memory usage of tcmalloc cannot be obtained by
GetNumericProperty. This accounts for the current_allocated_bytes,
fragmentation and malloc metadata, and excludes the unmapped memory
regions. This helps the user to understand how much memory is actually
being used for the allocations that were made.
