Make Blob constructor's first argument optional.

Make Blob constructor's first argument optional.

The spec previously had constructor overloads, allowing blobs to be
created with either `new Blob()` (no arguments) or `new Blob([data])`
(argument with array of blob parts). But unlike most APIs, calling as
`new Blob(undefined)` would throw, which is unexpected. The spec was
updated to remove the overload and make the first argument optional
instead.

A PR has been submitted to update web-platform-tests.
