<!-- start_original_pr_link --> Reverts: flutter/flutter#164317 <!-- end_original_pr_link --> <!-- start_initiating_author --> Initiated by: matanlurey <!-- end_initiating_author --> <!-- start_revert_reason --> Reason for reverting: `bin/cache` does not exist on a fresh checkout, and `echo bin/cache/...` will fail as a result. This blocked the google3 roll, but would also break new checkouts of Flutter, for regular users/contributors. <!-- end_revert_reason --> <!-- start_original_pr_author --> Original PR Author: matanlurey <!-- end_original_pr_author --> <!-- start_reviewers --> Reviewed By: {jtmcdole} <!-- end_reviewers --> <!-- start_revert_body --> This change reverts the following previous change: 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). <!-- end_revert_body --> Co-authored-by: auto-submit[bot] <flutter-engprod-team@google.com>
