Teach WebString about 8 bit strings
Previously we always upconverted strings backing WebString to have both a 16
bit and an 8 bit buffer whenever we converted a WebString to a string16.
There's no reason to store a shadow 16 bit buffer in the String for this use
case. It's just as fast to copy out an 8 bit buffer into a string16 as it is to
copy out a 16 bit buffer.
This CL removes the vast majority of the string up converstions for Mobile
Gmail. In a future CL, we should remove WebString::data() to prevent Chromium
code from accidentially upconverting the underlying String.
