Simpler reading methods for Blob interface

Adds three new methods to the Blob interface to perform read operations: text(), arrayBuffer(), and stream().

Right now, developers can read a blob with a nicely promisified and/or streamified API by do something like: new Response(my_blob).body .arrayBuffer(), .text() etc The Response wrapping trick feels like a hack, and especially as long as FileReader exists, isn't very discoverable.
