feat(resource/streaming): set timeout length and return requested item on success

[DokaDoka]

This is a bit of a mess since I've had it sitting around for about a month and I don't know how to split it up nicely at this point.

It's basically 2 parts:

• adds the timeout parameter
  allows the number of ticks before timeout to be specified, timeout is avoided if nil
  20 ticks was rarely enough for vehicle spawns

• returns the requested item on success
  basically just to return the vehicle hash so I don't have to joaat it twice
  added to the other functions for consistency

I haven't tested the functions aside from requestAnimDict and requestModel but everything should still function

Maybe something like this would be a bit nicer (I'll let you test it, don't want to load up FiveM atm).

local function hasLoaded(fn, type, request, timeout)
    timeout = timeout or 100
    while not fn(request) do
        Wait(0)
        timeout -= 0
        if timeout < 1 then
            return print(('Unable to load %s after %s ticks (%s)'):format(type, timeout, request))
        end
    end
    return name
end

100 ticks as the default is fine by me, will still need use a separate variable for timeout or it will always print 0
Vehicles often fail to load in time but everything else is likely fine
