Copy Valgrind scripts that was deleted from Chromium's tools/ to fix the Memcheck bot:
valgrind/chrome_tests.bat
valgrind/chrome_tests.py
valgrind/chrome_tests.sh
valgrind/common.py
valgrind/gdb_helper.py
valgrind/locate_valgrind.sh
valgrind/memcheck_analyze.py
valgrind/valgrind.gni
valgrind/valgrind.sh
valgrind/valgrind_test.py
valgrind_test.py was stripped of its Mac and Dr Memory specific parts, which
we don't use. There's still more cleanup to do, tracked in bugs.webrc.org/7849.
This is similar to changes in https://codereview.webrtc.org/2945753002.
