LibWeb: Add public get accessor function for Blob's internal ByteBuffer

Browse source 
Blob::bytes() returns the ReadonlyBytes representation of our internal
ByteBuffer.

This change requires us to ByteBuffer::copy() Blob's ReadonlyBytes to a
ByteBuffer in XHR::send() and corresponding error handling of the copy
operation.

This removes the need for Blob to declare XMLHttpRequest as a friend
class.
