Revert 289312 "Move StringToUpperASCII and LowerCaseEqualsASCII ..."

> Move StringToUpperASCII and LowerCaseEqualsASCII to the base namespace
> 
> Convert LowerCaseEqualsASCII to take StringPiece. In the current patch this is
> generally a NOP but will allow me to delete the other 4 variants in a followup
> (wanted to do that separately since that will require more review, since
> callsites will be changed in nontrivial ways).
> 
> In some cases, LowerCaseEqualsASCII is called with a WebString, which no
> longer is implicitly converted. I added base::string16(...) around such
> calls to force the right conversion. It happened in these files:
>   window_container_type.cc
>   savable_resources.cc
>   render_view_impl.cc
>   blink_ax_tree_source.cc
