Beschreibung
### Which Cloudflare product(s) does this pertain to?
D1
### What version(s) of the tool(s) are you using?
3.51.2 [Wrangler]
### What version of Node are you using?
21.6.10
### What operating system and version are you using?
macOS Sonoma 14.4.1
### Describe the Bug
### Observed behavior
When exporting a D1 database with some relations using `npx wrangler d1 export`, it can generate an SQL file that cannot be imported again (`✘ [ERROR] no such table: main.B`). This is due to INSERTs happening before all tables are created.
I've prepared a minimal reproduction repository: https://github.com/hrueger/d1-export-order
### Expected behavior
All `CREATE TABLE` queries happen first, all `INSERT`s afterwards.
### Steps to reproduce
See https://github.com/hrueger/d1-export-order
in short, you need two tables, where the first table has a foreign key to the second table. Insert one row each, export that and try to import it again using `npx wrangler execute ... --file ...`
In the minimal reproduction there's also a fixed sql file, where the `INSERT` is just moved to the bottom.
### Please provide a link to a minimal reproduction
https://github.com/hrueger/d1-export-order
### Please provide any relevant error logs
```
✘ [ERROR] no such table: main.B
```
As per our discord conversation on friday, I'm tagging @geelen. Thanks for looking into this!

Start with the minimal reproduction repository and run `npx wrangler d1 export`, then try importing the generated file with `npx wrangler execute ... --file ...`. Compare the generated SQL with the fixed SQL file, and verify that exports with foreign-key relations can be imported successfully, with all tables created before rows are inserted.
