On Windows we need to be able to create both Linux and Windows OCI spec
files by default to support WCOW and LCOW scenarios. This merges the
compile time differences into runtime differences between the two based
on the spec and platform the user sets.
It maintains the old behavior with Default specs resulting in the
platform default the binary is compiled for.

We introduce a WithSpecFromFile option combinator to allow creation
simpler creation of OCI specs from a file name. Often used as the first
option in a `SpecOpts` slice, it simplifies choosing between a local
file and the built-in default.
The code in `ctr run` has been updated to use the new option, with out
changing the order of operations or functionality present there.

This allows Go to build third party packages correctly without vendoring
issues what want to create their own SpecOpts.
