chore(TS) remove enums for string unions when enum is not necessary

[asturur]

Motivation

As per discussion, our use of enums isn't justified.
#8915 (comment)

Enums aren't supposed to be named dictionary of strings, we have union types for that.

There was also a possible bug in the glPrecision code in which we were transforming an object into an array, without knowing in which order we were loopin through precisions test

[asturur]

We could have a second PR in which we explore if common strings used over and over should be a constant.

i m moving forward with this, i don't see possible disagreemts since it spawned from your question.
In case i m fine reverting and re-opening.

This enum I liked
But it is ok to remove
I would add the p suffix in our code just to it make it more human and readable...
But I am sure there are legit reasons why not.
