re-support the UUID lookup

[johnnychen94]

We used to have @lazy import ImageCore stuff without uuid, and now it's @lazy import ImageCore = "uuid-of-imagecore" because the one argument identify_package("ImageCore") ruins the package compilation. https://github.com/JuliaLang/julia/pull/45287#discussion_r873871094

Might be worth trying if the two-argument version satisfies our need so that we can still use the convenient @lazy import ImageCore syntax.
