Coarse error trapping

[ef4]

First draft of an error trapping component that uses the same technique as our pre-render's isolated-render.

• make our isolated rendering environment do normal re-renders
• refactor the pre-render to be built on top of error-trap

[ef4]

The first major finding from attempting this is that our existing isolated pre-render doesn't support re-rendering. It's one-and-done.

The next bit of code I need to touch in ember is different between our current version (5.4) and newer releases, so I'm going to do the update first.

The stack is getting deeper. In the process of updating ember I hit the fact that our runtime card compile is still on the old ember-template-imports implementation rather than the new content-tag based implementation. So I'm working on updating that, then ember, then coming back to this pr.

First part of card transpilation toolchain upgrade is landed: #1771. Now it uses the same decorator transpilation that the rest of host uses.

Second part will be replacing @cardstack/ember-template-imports with content-tag. I started with that and hit a snag with fastboot wasm support.
