Add crosshair component to *playerHudComponentProperty functions

[FileEX]

Summary

This PR adds the crosshair component to the setPlayerHudComponentProperty, getPlayerHudComponentProperty, and resetPlayerHudComponentProperty functions. It allows you to change the size, position, and color of the crosshair.

Note

The crosshair is composed of 4 textures arranged in a 2x2 layout. The size specified in setPlayerHudComponentProperty defines the size of a single part of the crosshair, not the entire crosshair. On the other hand, the size returned by getPlayerHudComponentProperty represents the size of the whole crosshair; you can divide it by 2 to get the size of a single part.

Motivation

Closes #4553

Test plan

addEventHandler('onClientRender', root, function()
    local x, y = getPlayerHudComponentProperty('crosshair', 'position')
    local w, h = getPlayerHudComponentProperty('crosshair', 'size')

    dxDrawRectangle(x, y, w, h, tocolor(255, 255, 255, 100))
end);

I tested changing the position and noticed the white dot at the center stays in the same place:
