fix: memoize esm component getter/setter in hot.data (#26)

[katywings]

Background

This uses vite hot.data to store and recover previous component getter/setters. Without it, child components are not able to get updated after a change in the parent component, as mentioned in #26.

The goal of this fix was to change as few things as possible in solid-refresh, because as discussed with @lxsmnsyc solid-refresh is getting a proper larger rework soon-ish anyways.

Reproduction

1. Clone: https://github.com/katywings/solid-hmr-lost-signals
2. Disable the "overrides" section in "package.json"
   • The overrides section already includes my github repository with the fix
3. Follow instructions in https://github.com/katywings/solid-hmr-lost-signals

How did I test the changes

• I ran pnpm run test
• I used the "package.json" overrides feature to test this fix in my projects and the reproduction repository
  • Example of the overrides: https://github.com/katywings/solid-hmr-lost-signals/blob/2a1c40a8e32e3d7326c6c5bd27ff4eeeb1734cff/package.json#L23
