Warn on not-yet-supported import.meta usage (#2397)
This implements a warning when `import.meta` is referenced, both as a standalone expression (`import.meta`) and as a member expression (`import.meta.url`, `import.meta.foo`, etc.).
To do:
* [x] This expression covers both `import.meta` as well as `new.target`. Investigate how this usage is impacted and handle it.
Test Plan:
* Added a `import.meta` expression and `import.meta.url` member expression in a test app and verified both were flagged (see below)
* In the same test app, verified using `new.target` was not flagged.
```

1 > console.log(import.meta);
2 console.log(import.meta.url);

4 function Foo() {
5 new.target;
