This changes platforms.Parse to hit /proc to look up CPU info only when
it's needed, instead of in init(). This makes the package a bit easier
for other packages to consume, especially clients that don't call
platforms.Parse or need to lookup CPU info.

Adds a new platform interface for matching and comparing platforms.
This new interface allows both filtering and ordering of platforms
to support running multiple platform and choosing the best platform.

This test case should cover the variant field now, as we have
add Variant to default value of spec.platform.

For supporting selection of images and runtimes in the containerized
world, there is thin support for selecting objects by platform. This
package defines a syntax to display to users that can express specific
platforms in addition to wild cards for matching platforms.
The plan is to extend this to provide support for parsing flag
arguments and displaying platform types for images. This package will
also provide a configurable matcher to allow match of platforms against
arbitrary targets, invariant to the Go compilation.
The internals are based the OCI Image Spec model.
This changeset is being submitted for feedback on the approach before
this gets larger. Specifically, review the unit tests and raise any
concerns.
