Get GPUTracing lab script to listen to more user providers

Now that EventEmitter.exe can emit UIforETW style events it makes
sense for lab scripts to listen for more providers. This adds all
of the Multi-* providers (EventEmitter.exe's odd naming scheme) plus
Microsoft-Windows-Win32k (Windows in focus, etc.) and the
controversial but maybe useful Microsoft-Windows-Kernel-Memory.

Flags are used to control exactly what is recorded, although
figuring out what they mean is yet another dark art.

How much this increases the data rate of the traces depends primarily
on how noisy EventEmitter.exe is.
