refactor: migrate to @babel/parser

[pionxzh]

This PR replaces the existing parser from espree to @babel/parser.

There is only 1 failed test:

+ expected - actual

 class Foo {
-  bar() {
-    console.log(arguments);
+  bar(...args) {
+    console.log(args);
   }
 }

escope does not recognize ClassMethod from babel. I'm not sure how to fix it. This must be done on escope side.

---

I have verified that acorn and espree will trigger issue #352 , all other parsers are ok. But esprima is kind of dead. Typescript will run into the escope issue too. That's why I choose babel.

I started to want to patch recast by myself to fix the original issue. But maybe this PR is complete enough that you will have an interest in it. If you think this is not the direction to go, can close. 🙏

The only test I changed. According to the spec, the original "use strict" is just a string literal. So, I move it into the function body to make it a strict mode for function.

Thanks for the PR.
