A number of checks and pre/post processing is done for each executed function. Some of it can be known at compile time since it only depends on the function and the number of arguments. With this commit, we pre-compute a number of things only once at compile time to minimize what is done when executing the function.

Remove the layer that was adapting the return value of the compute formula by directly creating the values object within each compute function definition. This simplifies typing by reducing the number of different return cases that needed to be handled in the compute functions. Task: 6254300
Introduce a type-level distinction between formulas that return a scalar value and formulas that return an array. Previously, all formulas shared the same return type signature, making it impossible to enforce correct usage at compile time. This distinction will help in future commits to know, at compile time, what can be vectorized and what cannot. Task: 6254300
It is no longer necessary to check at each compute function whether vectorization is required. Now, the compilation tells us whether a formula needs to be vectorized or not. Task: 6254300
…ized args Instead of storing a boolean array where each index indicates whether an argument should be vectorized, store only the indices of arguments that need vectorization. This avoids iterating over all arguments and directly targets only the relevant ones. Task: 6254300
