This adds a feature to
@embroider/shared-internals
so that the env varEMBROIDER_FORCED_V2_PACKAGES
can cause any package to be interpreted as a v2 package regardless of what the package itself says.The initial motivating use case for this is that new-enough ember-source can function as a valid v2 addon despite not declaring itself to be a v2 addon, because that would be potentially-breaking for people who still consume it via AMD and/or depend on the specific timng of the classic vendor.js file. We don't want to break existing usage but we also want people on the bleeding edge to be able to take advantage of the capability.
