btrace: Add support for further events.

Browse Source 
This is similar to the previous events that we added, and adds support for
SMI, RSM, SIPI, INIT, VMENTRY, VMEXIT, SHUTDOWN, UINTR and UIRET.
Though since these are mainly mechanical and not really possible to test,
they are bundled in one commit.
