ntoskrnl.exe: Return zero for unknown msr registers.
...
rdmsr should fault if called with the register not supported
by CPU. But until we want to support the full range of CPU
specific registers returning zero is probably a better
fallback.

server: Add USD support with timestamp updates.
...
The USD page is created when the first process (wineboot.exe) completes
its creation, using its provided user_shared_data for initialization.
The server maps the page write-only and the clients map it read-only,
then the server updates the timestamps every 16 ms.
