Fix cookies are not imported from Chrome

[simonhong]

Since the V11 cookies db schema, firstpartyonly column is renamed to samesite.
Also, BraveImporter and ChromeImporter should have different cookies query
string because muon uses old schema.

Upstream changes: https://chromium-review.googlesource.com/c/chromium/src/+/1570416

I think we should update test/data/import/chrome/default/Cookies periodically for testing with latest chrome cookies db.

Oh, I found BraveImporterTest.ImportCookies failed. checking now.
Maybe its test cookies db should be updated also. -> fixed.

Tested with GitHub, importing from Canary. Works great! 😄 Super nice to have this fixed- thanks! 😄👍

Merged because CI has some internal error node disconnecting and I saw all binaries are built for all platforms from multiple CI trying.
