Link v3: Assets and component views

[davidme-stripe]

Summary

Bring back a grab bag of assets, colors, and component views for Link. These are all self-contained and don't change the current functionality, but will be used by the ViewControllers in later PRs.

The black and white Link logo in the snapshot tests is a known issue — we'll have updated logo assets before launch.

This code was all reviewed previously, but we should give it another look as we merge it back in.

Motivation

Link v2

Testing

Resurrected some snapshot tests

Changelog

None

If you are adding a new public API consider the following:

• Do these APIs need to be public or can they be protected with @_spi(STP)?
• If these APIs need to be public, assess whether they require an API review.

If you are modifying or removing a public API:

• Does this require a breaking version change?
• Do these changes require API review?

If you confirm these APIs need to be added/updated and have undergone necessary review, add the label modifies public API to this PR to acknowledge and bypass this check.
