I just want to ask few questions w.r.t utility types in typescript

Right now whenever we have to get a union of object values we have to do something like this

const stages = {
   LOADING : 'LOADING'
   ERROR: 'ERROR'
   SUCCESS: 'SUCCESS'
} as const 

type Stages = typeof stages[keyof typeof stages]

this becomes redundant in code base and can be improved with utility types for e.g.

type ObjectValues<T extends Record<any, any>> =  T[keyof T];

Willing to add this as a utility type provided by TS, but stuck on where to add this es5.d.ts is one place where I can write it but not sure if thats the correct place and do I need to add it somewhere else or not.

Nowhere. See #39522 (comment):

We've opted to not include utility type aliases in the lib unless they're required for declaration emit purposes.

Lol, time to create my own utility library then 😂

You're free to do so. Or use one of the many many out there.
