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.
-- v3: kernel32/tests: Add tests for GetProcessPriorityBoost/SetProcessPriorityBoost. kernelbase: Implement SetProcessPriorityBoost. kernelbase: Implement GetProcessPriorityBoost. ntdll: Implement ProcessPriorityBoost class in NtSetInformationProcess. ntdll: Implement ProcessPriorityBoost class in NtQueryInformationProcess. ntdll: Implement ThreadPriorityBoost class in NtSetInformationThread. ntdll: Properly implement ThreadPriorityBoost class in NtQueryInformationThread. ntdll/tests: Add tests for setting process base priority. ntdll: Implement ProcessBasePriority class in NtSetInformationProcess.

The `ProcessPriorityBoost` and `ProcessBasePriority` cases should also be added to the `wow64_Nt{Set,Query}InformationProcess` functions.
Thanks, should be fixed now.
The actual boosting mechanism will be in part 2 to keep the size of this MR manageable.
It's already too large, and there doesn't seem to be a reason to do all these changes at once. Please split into separate MRs.

I have split off the base priority process part (and that one is fairly self-contained) in https://gitlab.winehq.org/wine/wine/-/merge_requests/7939
