bit_util: Protect Replicate from automatic up-casting

Recursive calls to `Replicate` beyond the first call might
cause an unintentional up-casting to an `int` type due
to `|` and `<<` operations on types such as `uint8_t` and `uint16_t`

This makes sure calls such as `Recursive<u8>` stay as the `u8` type
through-out.
