Nested virtualization involves copying data between many different types
of VMCSes, e.g. vmcs02, vmcs12, shadow VMCS and eVMCS. Rename a variety
of functions and flags to document both the source and destination of
each sync.

There is an imperfection in get_vmx_mem_address(): access length is ignored
when checking the limit. To fix this, pass access length as a function argument.
The access length is usually obvious since it is used by callers after
get_vmx_mem_address() call, but for vmread/vmwrite it depends on the
state of 64-bit mode.

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.
