Sync gtest/gmock with Chromium's copy.
Copy over relevant files that are in Chromium's googletest, but not
PDFium's. Delete references to files that no longer exist. With these
changes, testing/gtest can pass "gn check".

+// TODO(crbug.com/1009553): Remove this wrapper after finding a way to plumb a
+// workable temporary path into googletest on Android.
+
+// This wrapper lets us compile gtest-port.cc without its stream redirection
+// code. We replace this code with a variant that works on all Chrome platforms.
+// This is a temporary workaround until we get good code upstream.
+//
+// Stream redirection requires the ability to create files in a temporary
+// directory. Traditionally, this directory has been /sdcard on Android.
+// Commit bf0fe874a27bd6c9a4a35b98e662d2d02f8879a2 changed the Android
+// directory to /data/local/tmp, which is not writable in Chrome's testing
+// setup. We work around this problem by using the old code for now.
+//
+// It is tempting to consider disabling the stream redirection code altogether,
+// by setting GTEST_HAS_STREAM_REDIRECTION to 0 in googletest's BUILD.gn.
+// This breaks gtest-death-test.cc, which assumes the existence of
