[heap-snapshot] Declaring progress counter as uint32_t (instead of int)

A test was overflowing on the progress counter when using int as type.
This CL is fixing the progress counter to use uint32_t, and re-enables
the test.

Why uint32_t instead of size_t?
In the referenced bug, the progress_counter_ (but not the
progress_total_) triggered an overflow; and since these two counters
should be relatively similar (the total count is an estimate, and can
be less than the actual progress count), we do not expect the
count to increase much more than we can already encode with int.
