[Console] Convert all lib/mappings files to typescript

[zhongnansu]

Coming from #3775 (comment), move to ts will make code more readable and maintainable.

Files:

find ./src/plugins/console/public/lib/mappings -name "*.js"
./src/plugins/console/public/lib/mappings/__tests__/mapping.test.js
./src/plugins/console/public/lib/mappings/mappings.js

✌️Hello!
Based on the issue, to increase readability and maintainability in those files, I'd like to suggest following

Suggestions:

• Add typings for the parameters, variables, and return values
• Update function signatures with TS types based on the typings above
• Replace typeof and Array.isArray with TS type guards
• Use TS utility types, such as Record and Partial
• Update the entire "lodash" import to individual functions import
• Add TS interfaces to provide type safety

Could you, please, assign this issue to me?

Feel free to comment or add more suggestions

Thank you!
Those are really useful for me and, yes, indeed I haven't seen them.
Today I'll finish typescripting files above.

Hi @Seitakhmetv, I hope you're doing well. I was wondering about the progress on this issue you've been working on. I'm looking forward to using the types from the mapping, as without them I can't complete my related Typescript conversion issue. Could you please provide an update on the status or an estimated time for completion? Thank you!

Hello, @Seitakhmetv @joshuarrrr Can I make a PR for this issue? My two other issues need types from this one to finish, so I'm currently blocked because of it.

[joshuarrrr]

@curq Yes, go ahead if you're ready to unblock the related work.
