[roll] Roll fuchsia [kernel][debug] left-align pointers and references. (format)

Fuchsia's clang format[0] has a directive to derive the source code pointer
alignment based on the most common use (`char *foo` vs `char* foo`).

The Google Style Guide[1] doesn't impose a formatting recommendation,
however, all their examples use left-aligned pointers. Based on the
recommendation of one of the owners of this file, the pointers should be
all left-aligned as well.
