Refactor to use `TaggedTemplateExpression`

[fisker]

Benfits:

• Won't trigger ASI (array expression or object/function/class expression may need parens some time, will need insert leading semicolon )
• Won't turn into a statement (object can parsed as a BlockStatement)
• Won't add parens around (object need parens when it's member expression head)
• suitable for other needs

If you want, I can help.

This branch was as far as I got with using a tagged template. There are 87 test failures I couldn't solve, but I was able to get everything passing without changing to the tagged template approach in this PR.

If you can show the tagged template approach would simplify the codebase here rather than complicate it I'd be interested.

I tried a little bit, it seems TaggedTemplateExpression has its own issue with binary expression. content-tag didn't mark statement.

content-tag should have run before the templates are replaced by the preprocessing code 🤔

I mean

prettier-plugin-ember-template-tag/src/parse/preprocess.ts

Line 33 in af77c81

if (template.type === 'class-member') {

should be "decoration" | "expression" | "class-member" instead of "expression" | "class-member"

To distinguish

<template></template> // decoration

and

<template></template>; // expression
