file.stream() is slow and CPU-bound
https://bugs.webkit.org/show_bug.cgi?id=235448

Reviewed by Alex Christensen.

We introduce a ReadAsBinaryChunks mode to prevent storing the whole file in memory.
Use this in Blob stream implementation.
The new implementation is much faster for big files given it does not need to keep in memory the whole file.
Covered by existing tests.
