move ember debug tests into own app

[patricklx]

ember debug is the thing that should/can be tested with older ember versions.
for inspector ui its not required. we can extend it for it as well though.

test fixed by mostly using setComponentTemplate as dynamic template resolving has been deprecated

This also

• adds back support for ember alpha+, ember/index has been removed and we have ember/barrel now
• fixes some InElement support issues with ember 6.4

Since this PR changes the usage of ember-try in the repo, I would be tempted to add ember-lts-5.12 to the configuration (and it's green locally ✅) IMO that could be a good iteration before investigating 6.x in a later PR :)

here we inject ember debug into the test app

To be fair I don't understand 100% all the details of all the changes so I would use at least one second opinion (cc @mansona) but this iteration looks fine IMO. The general approach to separate UI tests and ember_debug tests makes sense to me + fixing all the ember-try scenarios recreates more confidence in the test suite.

(Purely on the form, I think enabling 6+ and fixing 3.16~3.24 could have been done in 2 separated PRs, but I woundn't consider this a blocker since the commit stack is clean)

Hi @patricklx, I've an update about this PR.

@mansona has initiated a task to improve the "start wrapper" part of the inspector, based on his work on Rollup. This would enable the possibility of importing an adapter, so we wouldn't have to re-implement an adapter in each test app. We suggest keeping the present PR on hold until Chris has finished that work, then we can rebase and include this improvement.
