refactor(toolchains): configure prebuilt and from-source tool toolchains (#4280)

Configure prebuilt tool binaries when consuming a release archive, and
build
tools from source when developing rules_python or overriding with a git
commit. For now, using these prebuilt binaries are disabled for release
archives.

To make this work, MODULE.bazel has a boolean that decides whether
rules_rust et al are dev dependencies. By default, they are not dev
dependencies. This default is chosen so that sub-modules for
testing use the from-source toolchains and that using non-release
commits also use the from-source toolchains. When creating the
release archive, this value is rewritten to make them dev dependencies.
This means release archives can't use from-source toolchains unless
they patch MODULE.bazel (and likely more), but this seems like
a reasonable trade-off for complexity vs configurability.

The cargo lock files are required because rules_rust forces non-dev
dependencies of it to provide such lock files.
