[roll] Roll fuchsia [kernel][vm] Populated bytes: Identify disconnect with GetAttributedMemory

There are two known cases in anonymous hierarchies that the continuously
tracked populated slots count disagrees with GetAttributedMemory's
total_bytes field (total_bytes is reported as populated_bytes in
`zx_info_vmo_t`, leading to some confusion).

1. When there is a spurious parent content marker after ReclaimPage in a
parent. 2. When there is a spurious parent content marker after
DedupZeroPage in a parent.

Updates an existing test with documentation about 1., and adds a new
test to document 2.

There is work planned to ensure that these two "populated" metrics
converge in anonymous hierarchies.

Test: fx qemu -c 'kernel.compression.strategy=lz4 kernel.compression.storage-strategy=slot '; k ut continuous_attribution
