Define generic operation for GetDesiredSize?

[rombel]

In current version of the spec, ReadableStreamDefaultControllerGetDesiredSize and ReadableByteStreamControllerGetDesiredSize describe exactly the same process (this is because queueTotalSize is now used for both controllers). Wouldn't it be possible to define a single ReadableStreamControllerGenericGetDesiredSize, similarly to what is done for some reader operations?

Yeah, sounds fine.

Now that we're linking the internal slots, this seems less good.
