[release-branch.go1.17] runtime: store consistent total allocation stats as uint64
Currently the consistent total allocation stats are managed as uintptrs,
which means they can easily overflow on 32-bit systems. Fix this by
storing these stats as uint64s. This will cause some minor performance
degradation on 32-bit systems, but there really isn't a way around this,
and it affects the correctness of the metrics we export.
For #52680.
Fixes #52688.
