Subject: ipa: ipu3: Use libcamera::utils::Duration helper class for durations

std::chrono::Duration is provided quite conveniently by
libcamera::utils::Duration wrapper. Port IPAIPU3 to use that
for duration-type entities (such as exposure time), such that
it becomes consistent with rest of the codebase.

The commit doesn't introduce any functional changes.
