Key press delay for toggling the sirens depends on FPS limit

[Timic3]

Describe the bug
To toggle sirens for a specific vehicle, you need to press horn key in a quick order. How quick depends on the FPS limit, which isn't really ideal.

To Reproduce

1. Set FPS limit to 100
2. Toggle sirens using horn key - it's very unlikely that you will succeed
3. Try with 25 - it will be easier

Expected behavior
The delay between key presses should be same as on 25 FPS limit (I believe the game is supposed to run on 25 FPS).

I think this is obvious but I will say it anyway, this probably happens because the game checks how many frames did you keep pressed the horn button, if it's more than X ammount then the sirens turn on, else you just press the horn.

This can be work arround if you use setVehicleSirensOn.

0x5002C0 would seem to be responsible for this.

Needs a frame rate fix (https://github.com/multitheftauto/mtasa-blue/blob/master/Client/multiplayer_sa/CMultiplayerSA_FrameRateFixes.cpp).

Added to framerate fixes project.
