Current placeholder syntax uses attributes:

@@uncurried

let add = (x,y,z) => x+y+z

let ptl1 =  @res.partial add(1)

let v1 = ptl1(2,3)
Js.log2("v1:", v1)

Add surface syntax for partial application of uncurried functions

Fixes #6165

This PR introduces a new surface syntax for partial application of uncurried functions in ReScript. The syntax allows developers to partially apply uncurried functions more easily and concisely using the ... token in argument lists. The implementation includes changes to the parser, grammar, and printer to handle the new syntax properly.

Example:

res
Copy code
let add = (a, b) => a + b
let ptl1 = add(1, ...)
let result = ptl1(2) // result will be 3
This example demonstrates the new syntax for partial application of the uncurried add function.
