Bump embroider libs to v1

[jrjohnson]

Making the same embroider changes as #2327 to the v2 branch to help resolve embroider-build/embroider#1077 hoping this won't require bumping ember-auto-import as well now that there is a compatible 1.x version release there.

@jrjohnson so the problem is that ember-cli-mirage@2 has support for Node.js 10 and @embroider/macros needs 12+ as of 0.42.0

@jrjohnson I think we can release [email protected] so people can start using it if they have fixed all the deprecations (I'd like to get #2314 into beta at minimum)

@cah-briangantzler wdyt?

[jrjohnson]

Ah. Makes sense. We'd be happy to jump to an early 3.0 release. Always easy to beta test test libs 😁

[SergeAstapov]

@jrjohnson I'll try to push #2314 over the line and get early v3 alpha sooner than later

[cah-brian-gantzler]

3.0 is mostly removing code. I have a PR for another deprecation im working on.

We can get a 3.0 out after we remove all the code, should be a problem if you want to beta it

[jrjohnson]

Ok, I'll close this. If there is anything I can do to help with removal I'm jrjohnson on discord.

@jrjohnson just published v3.0.0-alpha.1 🚀. Please give it a try and report any issues
