[PATCH v2 0/11] MR7869: Thread priority boosts (part 1)

[Marc-Aurel Zent (＠mzent)]

This implements setting `ThreadPriorityBoost`, `ProcessPriorityBoost`, `ProcessBasePriority` and getting `ThreadPriorityBoost`, `ProcessPriorityBoost` NT info classes and adds tests where appropriate.

The actual boosting mechanism will be in part 2 to keep the size of this MR manageable.
