feat: Allow bypassing invalidateAll in enhance

[tcc-sejohnson]

Closes #9476.

Adds an invalidateAll option to the callback from enhance. Setting this option to false will cause enhance not to skip the invalidation step.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

Hmm. I'm not sure I love this pattern of adding more options to update. As mentioned in #9476, we already provide the tools to achieve the desired outcome; this might be superficially more convenient, but it's API clutter that leaves us with multiple ways of doing things.

With hindsight I sort of wish we hadn't added the reset option but instead focused on composable APIs.

Let's either choose to do this or close this PR. I'm for merging it (not because I'm the author, just because it's useful) -- I agree we can probably come up with a better / more declarative API for v2, but this is, IMO, a good solution for now.
