Update Promise.all/allSettled/race/some/any

[Validark]

• all no longer accepts non-promises in the input array
• allSettled now preserves array/tuple length where possible

all/allSettled/race/some/any now all:

• accept readonly arrays, since these methods don't mutate in-place
• accept arrays with different Promise types in them, e.g. [Promise<number>, Promise<string>] now works

for race/any, we transform [Promise<number>, Promise<string>] into Promise<number | string> rather than Promise<number> | Promise<string>. For some it is the same but an array: Promise<(number | string)[]>
