Subject: ipa: ipu3: Tidy-up includes

Tidy-up a bit the inclusions directive in the IPU3 IPA module.

In detail:
- ipu3.cpp is missing inclusions for:
  std::abs from <cmath>
  std::map from <map>
  std::min/max from <algorithm>
  std::numeric_limits from <limits>
  std::unique_ptr from <memory>
  std::vector from <vector>

  and does not require <sys/mman.h>

- ipu3_agc has two not used inclusions in the header file and one the cpp file
  and is missing <chrono> for std::literals::chrono_literals

- ipu3_awb is missing <algorithm> for std::sort and does not use
  <numeric> or <unordered_map>
