Infra/modifiers perf improvement

Description

Update some modifiers extraction methods to improve performance.
I checked a specific session (on the private demo app, iOS) before and after these changes. the results are in ms:

before: {
  "backgroundColor": 291.95974069833755,
  "color": 1362.02895539999,
  "typography": 878.3454459905624
},
after: {
  "backgroundColor": 54.971199452877045,
  "color": 97.36799198389053,
  "typography": 85.1839787364006
},

Also, I added a function to update the modifiers' colors that should be called after loading some colors/scheme.
(and I call it on private in preset.config.ts)

Improve modifiers' performance

If you'll think about it, maybe it's better that the Colors class will maintain this logic and provide a cached list of colors keys.
By moving this logic to the Colors class, you can also update the cached list whenever loadColors is being called - so you don't need to worry about it as a consumer.
WDYT?

I wondered about it.. you can see my note in this PR description: https://github.com/wix-private/wix-react-native-ui-lib/pull/2473

Oh ok, I didn't see the private PR yet.
I think we should call and keep it in the Colors class, what are the cons for doing that?

[lidord-wix]

The only disadvantage I can think of is that it'll cause an overhead in the loadColors method in a case that the user calls it many times in his app.. but I guess it's a rare case and we can ignore it
I'll update it :)
