Refactor VA facility link in search result components

[mpelzsherman]

The VaFacilityResult and Covid19Result components have the following duplicated code:

          {isVADomain(website) ? (
            <h3 className="vads-u-font-size--h5 no-marg-top">
              <a href={website}>{name}</a>
            </h3>
          ) : (
            <h3 className="vads-u-font-size--h5 no-marg-top">
              <Link to={`facility/${location.id}`}>{name}</Link>
            </h3>
          )}

This code also lives in LocationInfoBlock.jsx.

Let's put this code into a common component and re-use that instead.

Confirmed this is still an issue in the code. There's also a near-identical other instance of this in LocationInfoBlock.jsx that could be included as well.
