Remove `feature_flags_legacy_read_only` feature flag
What does this MR do?
feature_flags_legacy_read_only feature flag is enabled on gitlab.com globally for a while. As it's confirmed as deemed stable, this MR removes the flag.
feature_flags_legacy_read_only_override was introduced for disabling the feature on the specific project with enabling it globally. Since it's not used at all today, we can remove it as well.
