Streamline template compilation, part 2

[ef4]

#1242 refactored the stage1 (addon compatibility) template compilation to use the new capabilities of babel-plugin-ember-template-compilation 2.0-alpha.

This PR will do the same for the stage3 (final app build) template compilation.

TODOs and areas to cleanup:

• app.ts babel config changes
• load-ember-template-compiler.ts
• babel-plugin-inline-hbs-deps*
• template-compiler-node.ts
• template-compiler-common.ts
• patch-template-compiler.ts
• ember-template-compiler-types.ts
• core/src/resolver.ts
• compat/src/resolver.ts
• release babel-plugin-ember-template-compilation

Next steps here:

• refactor the resolver tests, probably using code-equality-assertions since we're eliminating the need for the explicit dependenciesOf API
• switch most cases to use lexical scope. The only case that can't is a component with an un-associated template.
  • need to confirm that {{component}} helper is OK with taking lexically scope component classes as input (for the cases where it's being used for currying and can't just be replaced outright)
