Enable PRINTF_FORMAT for clang
This ports
https://chromium-review.googlesource.com/c/chromium/src/+/599127 from
Chromium to PDFium.
Because VC++ does not have format-string checking for user-defined
functions during normal compiles, because clang-cl had its format-string
checking disabled, because some files are only compiled on Windows, and
because VC++'s /analyze doesn't build all targets, and because VC++'s
format-string checking is more lenient than clang's... 50 warnings about
format-string mismatches crept in to Chromium's build. Seven of these
were somewhat serious, with four being wchar_t*/char* mismatches because
of base::FilePath and the other three being size_t/%d mismatches.
Now that all of the mismatches are corrected this change enables
PRINTF_FORMAT checking with clang-cl so that these bugs never return.
