gdata: Rename *OnIOThreadPool() to *BlockingPool()

The latter is consistent with BrowserThread::GetBlockingPool().
Besides, the term "IO" is infamously confusing in Chrome (you
cannot do file operations on IO thread).

Along the way, place IsRunningSequenceOnCurrentThread(sequence_token_)
in member functions that should be run on the blocking pool.
Update comments as well.
