template-tag code mod

[void-mAlex]

still WIP but sharing for progress tracking/early feedback
compatBuild alternative for running an app code through embroider… to get gjs/gts files

//ember-cli-build.js

const { templateTagCode } = require('@embroider/compat');

-return compatBuild(app, Webpack, opts);
+return templateTagCode(app, {shouldTransformPath: (component_path) => true});

builds upon base branch to get correct importable paths for 'builtIn' helpers/modifiers/components

Generally has the right shape.

It would be good not to need to know about the structure of #embroider_compat/ imports. Ideally all imports would be passed to the resolver to decide what to do with and based on the output path discovered the codemod would decide to inline that result or leave it unresolved.

I know this is still draft but we tried it on a reasonably large app and came up with a few problems 🙈 I'll list them here but please ignore if you're not in the mode for feedback 👍

• there are a few places where you're using __dirname to find the embroider build but it should be using process.cwd()
• this whole system seems to break if you have a babel config file (i.e. for a vite run) so we need to figure out the babel config setup for running files
• if you have a basic babel config file with just a typescript plugin this process fails because it needs to parse your app using your app's babel config e.g. ember-concurrency transform. We probably need to use the same process that embroider uses to load the config
• we're missing an export from @embroider/compat
• babel-plugin-ember-template-comilation is being looked for relative to the app rather than relative to @embroider/compat so we probably need to find it using require.resolve before passing it to babel
