[webkit-dev] Update WebKit style to better accommodate accepted Obj-C block syntax

[Megan Gardner]

Currently, the webkit style checker does not allow ^{ at the beginning of Obj-C blocks. It demands that there is a space between the ^ and the {. This is not how obj-c code is usually styled, and there is plenty of code already in webkit that is formatted with the carrot and and brace together. This seems to have been changed recently with https://bugs.webkit.org/show_bug.cgi?id=161247. I think we should revisit this, as ^ { is much less common that ^{ and is canonical style in pure Obj-C.
