Default to bazel with minimal embedded JDK.

This will save ~22MB of the final bazel binary and ~120MB in the
install_base.

RELNOTES[INC]: //src:bazel uses the minimal embedded JDK, if you want to
avoid the extra steps of minimizing the JDK, use //src:bazel-dev
instead.

Closes #7049, part of #6314.
