Implemented FSUser::CreateExtSaveData

Stubbed some services

dyncom: Minor cleanup

Removes some unused macros and cleans up indentation inconsistencies

Fix WaitSynchronization

- ReleaseNextThread->WakeupNextThread
- ReleaseAllWaitingThreads->WakeupAllWaitingThreads.

- Would deadlock the calling thread
- Code would never get hit anyways

- Separate wait checking from waiting the current thread
- Resume thread when wait_all=true only if all objects are available at once
- Set output to correct wait object index when there are duplicate handles

Added HID_SPVR service and split HID_U implementation into hle/service/hid/hid.xxx

Add option to hide dock widget title bars

core_timing: Mark several variables as static

core: Fix a few docstrings
