LOG: [ODS][NFC] Cast range.size() to int32_t in accumulation (#85629)

Using range.size() "as is" means we accumulate 'size_t' values into
'int32_t' variable. This may produce narrowing conversion warnings
(particularly, on MSVC). The surrounding code seems to cast <x>.size()
to 'int32_t' so following this practice seems safe enough.
