Bug 1461225 [wpt PR 10977] - Test BigInt as keys and values in IndexedDB, a=testonly 

Automatic update from web-platform-testsTest BigInt as keys and values in IndexedDB (#10977)

BigInt and BigInt wrappers are supported in serialization, per
https://github.com/whatwg/html/pull/3480
This support allows them to be used as IndexedDB values.

However, BigInt is not supported as an IndexedDB key; support
has been proposed in the following PR, but that change has not
landed at the time this patch was written
https://github.com/w3c/IndexedDB/pull/231
