Subject: Run clang-tidy modernize-use-equals-{delete,default} on
 //third_party/pdfium

See the bugs and cxx post for justification and details:
https://groups.google.com/a/chromium.org/forum/#!topic/cxx/RkOHzIK6Tq8

This change was done using clang-tidy as described here:
https://chromium.googlesource.com/chromium/src/+/lkcr/docs/clang_tidy.md

In some cases the the tool leaves behind a string of commas where it
replaced a member initializer list
(https://bugs.llvm.org/show_bug.cgi?id=35051). They were cleaned up
with:
  git diff --name-only | \
      xargs sed -E -i 's/(^\s*|\)\s*):[ ,]*= default/\1 = default/'

Bug: chromium:778959, chromium:778957
