LibJS: Make DataView::byte_offset() return u32
This fixes structured serialization of DataView. It was expected to be uniform with TypedArray, which returns u32 for byte_offset(). This was covered by a number of WPT infrastructure tests, which this commit also imports.

/**
|

* Runs a collection of tests that determine if an API implements structured clone
|
||||
* correctly.
|
||||
*
|
||||
* The `runner` parameter has the following properties:
|
||||
* - `setup()`: An optional function run once before testing starts
|
||||
* - `teardown()`: An option function run once after all tests are done
|
||||
* - `preTest()`: An optional, async function run before a test
|
||||
* - `postTest()`: An optional, async function run after a test is done
|
||||
* - `structuredClone(obj, transferList)`: Required function that somehow
|
||||
* structurally clones an object.
|
||||
* Must return a promise.
|
||||
* - `hasDocument`: When true, disables tests that require a document. True by default.
