rts/ProfHeap: Ensure new Censuses are zeroed
When growing the Census array ProfHeap previously neglected to
zero the new part of the array. Consequently `freeEra` would attempt to
free random words that often looked suspiciously like pointers.
Fixes #21880.
(cherry picked from commit e2f0094c315746ff15b8d9650cf318f81d8416d7)
