Historically, many of these enums used `const enum`s, which at least had the benefit of being compiled away at build time. We've now moved to mostly normal `enum`s, which are both less efficient than normal constants, and a relic of an earlier TypeScript era before literal types. This PR moves all enums to normal constants, and creates types for the constant values when the code needs them.

Local results are "no change". I would have expected at least a small change, but the main motivation for this change was to move away from enums and const enums in favor of normal constants and literal types, which eliminates a dependency on increasingly non-standard compilation infrastructure. So no news is good news. |

No perf difference on either of our local tests -- CI thinks improvement, so we'll merge. |

This PR ended up being much more extensive than originally intended because it ended up including quite a bit of cleanup to the benchmark setup and cleaned up mistakes in the
package.jsons that were causing subtle issues in the benchmark environment.[EDIT] @NullVoxPopuli pushed me to extract a lot of the incidental changes into their own PRs. I did quite a bit of that and it did streamline this PR. Thanks @NullVoxPopuli!
