Support architecture for dependencies

[c0d1ngm0nk3y]

Describe the Enhancement

When resolving a buildpack dependency, the architecture should be taken into account. That would allow the same version to be present for different architectures (e.g. arm and amd). This would allow arm support for buildpacks using packit.

Possible Solution

The Resolve function should take the architecture in consideration when looking for a dependency. Similar to the Resolve function in libpak. But the solution should be less "hacky" (e.g. taking the architecture from a property rather the purl)

Motivation

paketo-buildpacks/nodejs#995

In order to get arm support for the nodejs meta buildpack, there must be a way to filter dependencies on their architecture.
