Add --bazel-mode and --bazel-mode-dev

This allows "bazel mixed builds prod mode", in additional to reworking
the mechanism in which mixed builds dev mode is enabled.

As a followup, CI scripts will be migrated to use the new flags, as
USE_BAZEL_ANALYSIS=1 is deprecated.

Test: Manually ran --bazel-mode with an allowlist verifying that the
module alone was enabled
Test: Manually verified --bazel-mode and --bazel-mode-dev cause a build
failure
