[IndexFilters] consolidate se23 styles and logic (#10230)

<!--
  ☝️How to write a good PR title:
- Prefix it with [ComponentName] (if applicable), for example: [Button]
  - Start with a verb, for example: Add, Delete, Improve, Fix…
  - Give as much context as necessary and as little as possible
  - Prefix it with [WIP] while it’s a work in progress
-->

### WHY are these changes introduced?

Fixes #9938 

### WHAT is this pull request doing?

* Consolidate se23 styles 
* Consolidate se23 logic
* Remove custom `FilterButton` and replace it with direct invocations of
the Polaris Button instead. This seems safe to do because:
* even though we export `FilterButton` from the root of `IndexFilters`,
we do not actually expose it directly from the `polaris-react`
[entrypoint](https://github.com/Shopify/polaris/blob/2c718dc3ecf9393119cd1e08c387b648db78449a/polaris-react/src/index.ts#L190).
* AFAIK, noone is reaching into our cjs/esm builds to grab`FilterButton`
(see
[grokt](https://grokt.shopify.io/results?q=%40shopify%2Fpolaris%2F.*%2Fcomponents%2FIndexFilters))
* Just to be sure, also doesn't look like anyone is importing
`FilterButton` from @shopify/polaris either. (see
[grokt](https://grokt.shopify.io/results?q=FilterButton))
* That said I can see an argument being made for providing convenience
wrappers to alleviate repetitive config, so deferring to the team. 👍
Happy to revert if necessary 👍
