John Stiles e58831cd95 Add format-specifier warnings to SkDebugf.
This CL fixes up many existing format-specifier violations in Skia.
Note that GCC has a warning for formatting nothing, so existing calls to
`SkDebugf("")` have been removed, or replaced with `SkDebugf("%s", "")`.
These were apparently meant to be used as a place to set a breakpoint.

Some of our clients also use SkDebug with bad format specifiers, so this
check is currently only enabled when SKIA_IMPLEMENTATION is true.
