Summary:
react-native-windows builds treat a lot of c++ compiler warnings as errors. Including ones that cause value truncation when assigning `size_t` values to an `int`.
This fixes the compiler warning, by using `size_t` as the type for `i`, which matches `size`. I then modified the loop to avoid the value underflow that occurs when decrementing an unsigned zero value.
## Changelog
[Internal] [Changed] - Fix compiler warnings around mixing int and size_t usage in unsafe ways
