Vague "Statement too long" error when importing large SQL files into D1

Proposed changes

I want to suggest adding a less vague error description for the "Statement too long" error message received when you go to import a large sqlite database file to Cloudflare D1 using Wrangler. It'd be helpful to include somewhere the maximum size of a statement, whether it's the data size or lines of SQL. Additionally, it would be good to have documentation explaining why it occurred and adding a simple troubleshooting suggestion to fix the issue, which can easily be fixed by converting a large statement into multiple statements or simply reducing the file size via lines of code or otherwise.

Subject Matter

An explanation of the error, step-by-step instructions to break down large SQL statements, and offering code examples to demonstrate the suggested approaches.

Update: Since this Issue, we have added a new section for troubleshooting this particular error here

Also, our maximum SQL statement length, and our maximum row lengths are both documented in out limits page.

There is another issue/internal effort to consolidate D1 errors in one page.
