The kernel now permits userspace to read IA32_VMX_MISC_MSR MSR to operate the VMX preemption timer in commit 7441046. This commit updates the manual to reflect that. Since the seL4 version in Microkit had been recently bumped which included that commit.

IDK why we need a long list of everything supported tbh.

Actually, yeah. I think I changed my mind. I'm guessing there's an x86 reference for these registers? I don't think we should list all of them here, it's unwieldy.
