[dds] Roll chrome_tag, browser_launcher_rev, and add --use-mock-keych…

…ain flag to dds

With this roll, Chrome now triggers a dialog on MacOS requesting
credentials. This results in timeouts for
pkg/dds/test/devtools_server/remote_control_test. To avoid user
input, we use a mock keychain instead. The same change has gone
into browser_launcher_rev, and so we include that commit here.
