55d2375e58 KVM: nVMX: Move nested code to dedicated files
From a functional perspective, this is (supposed to be) a straight
copy-paste of code.  Code was moved piecemeal to nested.c as not all
code that could/should be moved was obviously nested-only.  The nested
code was then re-ordered as needed to compile, i.e. stats may not show
this is being a "pure" move despite there not being any intended changes
in functionality.
