Write an identical value to bin/cache/engine.stamp to prepare for migration (#164317)
Towards https://github.com/flutter/flutter/issues/164315.

This PR just writes `bin/cache/engine.stamp` identically to how
`bin/internal/engine.version` would otherwise be written, with a caveat
that _if_ `engine.version` is tracked, it is now _copied_ to
`bin/cache/engine.stamp`.

After this lands, I'll send PRs to update tooling that looks for
`engine.version` and give a heads up to the larger team (i.e. Dart HH
bot or whomever we will break by doing this).
