Adds support for ArrayBuffer and all typed array views (except for DataView) in the remote module.

Also makes the IPC payload much smaller (in the net module tests the payload goes down from approx 13 KB to 5 KB) by using base64 encoding instead of an array of values.

for example when calling electron.remote.getCurrentWindow().getNativeWindowHandle(); this is the JSON with the return value

before:
[{"type":"buffer","value":{"type":"Buffer","data":[32,72,27,0,64,96,0,0]}}]
after:
[{"type":"buffer","value":{"type":"Buffer","data":"oAzG+9B/AAA="}}]

Also calling Buffer.from(value) instead of Buffer.from(value.buffer) would create an unnecessary copy of the data instead of just creating a different view of the underlying memory.

https://nodejs.org/api/buffer.html#buffer_class_method_buffer_from_buffer

Copies the passed buffer data onto a new Buffer instance.

https://nodejs.org/api/buffer.html#buffer_class_method_buffer_from_arraybuffer_byteoffset_length

This creates a view of the ArrayBuffer without copying the underlying memory. For example, when passed a reference to the .buffer property of a TypedArray instance, the newly created Buffer will share the same allocated memory as the TypedArray.
