Flip --incompatible_require_ctx_in_configure_features

    Last run of the CI (https://buildkite.com/bazel/bazelisk-plus-incompatible-flags/builds/124) shows only Tensorflow and Envoy issues. Envoy is fixed by envoyproxy/envoy#7058, and Tensorflow is fixed in Bazel@HEAD by bazelbuild/bazel@cab65ff.

    RELNOTES: Incompatible flag `--incompatible_require_ctx_in_configure_features` has been flipped. See bazelbuild/bazel#7793 for more information.
