script: Add a Constraint DOMException for IndexedDB (#37605)
Add Constraint DOMException to handle the name conflict error in
`IDBDatabase::createObjectStore` method.

Testing: `./mach test-wpt tests/wpt/tests/IndexedDB/`, but it seems
there are many test failures even in main branch already ([related
comment](https://github.com/servo/servo/pull/37605#issuecomment-2993889163)).
Fixes: #37571
