perf(dashboard): Improve performance of the native filters config modal

[kgabryje]

When user has a big dashboard and many native filters added, the filters config modal is very laggy and unresponsive.
We should:

1. Improve the structure of components that build filters config modal (for example FiltersConfigForm has over 1200 lines...)
2. Reduce the number of unnecessary rerenders (with React.memo, useCallback, useMemo). To measure and find unnecessary rerenders I recommend library whyDidYouRender
3. Measure the performance of filters config modal with Chrome devtools and try to optimize anything that stands out.

@kgabryje should we consider this closed after the aforementioned merged PRs?
