Bug 1927492 [wpt PR 48841] - [WebNN] Fix DCHECK(!isShared()) failure of reading MLTensor, a=testonly

Automatic update from web-platform-tests
[WebNN] Fix `DCHECK(!isShared())` failure of reading MLTensor

There is a `DCHECK(!isShared())` failure when trying to read MLTensor
to a shared array buffer. This CL uses `ByteSpanMaybeShared()` instead
of `ByteSpan()` for both `DOMArrayBufferBase` and `DOMArrayBufferView`
to read MLTensor on blink side to fix this issue, and also expands the
existing tests to verify this fix.
