Emulator 29.0.5 Canary

Emulator 29.0.5 is now available in the Canary and Dev channels. Changes:

• Fixed a long-standing issue with the Windows emulator where sub-processes (such as adb commands) failed to start if the username had spaces in it.
• Foldable emulator now preserves folded/unfolded state across snapshot saves and loads.
• Improved error message and added links to documentation on hypervisor setup if hypervisor initialization fails.
• Fixed missing initialization of RCU in HAXM vCPU threads. This can possibly address some crashes and race conditions.
• Fixed crash that happened in certain patterns of saving and loading snapshots from the snapshots UI in recent Q system images.
• Fixed issue where virtual scene camera was blank because emulated device state would be initialized improperly from snapshot if an AR macro was playing while that snapshot was saved.
