GDI patching (inconsistently) results in delayload crashes due to the
sandbox restrictions applied to various processes. In an effort to catch
all processes which need the patching, we applied it to all utility
processes. However, this has proven to be too inclusive, as many of
those processes have sandboxes which prevent this code from working
properly. This change detects the sandbox type and only executes the
patching if the sandbox type is ppapi, PrintCompositor, or PdfConversion.
