The `extra_bazel_features` attribute was added lowRISC#25840 as an attribute to `rv_rule` to transitively add features to the rule. However this is too general because when applied to opentitan_binary, it will change the features not only for the rule, but all its dependencies such as exec_env, tools, etc which may have unintended effects. This commit keeps essentially the same logic but instead of applying it to `rv_rule`, it is now only an attribute of `opentitan_binary` and `opentitan_test` and it transitions only features for the `deps`. This attribute is also renamed to `transitive_features`. The rationale for the rename is that every bazel rule has an implicit `features` argument but it only applies to the target, not its dependencies. This attribute does the same but also applies transitively. Signed-off-by: Amaury Pouly <[email protected]>
