Add SplitOnRestElement, ExtractRestElement, ExcludeRestElement types

[benzaria]

• SplitOnRestElemnt - Splits an Array on its Rest element portion into three parts: [[...Head], Rest[], [...Tail]].
• ExtractRestElemnt - Returns the rest element type from and array.
• ExcludeRestElemnt - Create a array with the rest element removed.

Creadit to @som-sm for introducing CollapseRestElement I modified a version of it to fit my needs, due to VariablePartOfArray not working as wanted for Optional elements.

@benzaria Please take the time to thoroughly check your PRs before requesting a review.

@som-sm So sorry for the mistake, we just had a Code Blue emergency in the block we needed to move fast.

[som-sm]

That’s fine, please take your time. Just make sure to double-check your work before requesting a review.

@som-sm I run it thru AI sanitizing any typos and bad grammar.

[som-sm]

I'll try to give it a proper read tomorrow.

BTW, these types should probably be suffixed with Rest instead of Spread. The TS handbook also refers to them as rest elements.

I'd also suggest suffixing them with Element, so SplitOnRestElement, ExtractRestElement & ExcludeRestElement.

[benzaria]

Sure !

@som-sm I think I resolved all ur comments.
