Similarly to what we've done earlier in the year for other tests [1], this patch disables entire *_browsertest.cc files by making them empty via chromium_src overrides, as well as all the JS tests via a patch to include_js_tests.gni, so that we avoid running any test that we know are going to fail because of the many ways in which Brave is different than Chromium upstream.
