Disallow changing element size of the static array property on the Editor

[TokageItLab]

The static hint for array property makes the array static.

It prevents movement, but does not prevent array size changes. Fix this by hiding the "Clear button" and "Add element button" as well as the Move element grabber.

Why would static need to be kept the same size? Static is not the same as constant.

[TokageItLab]

I don't know clearly what static means, since there are no properties that use static internally to begin with.

However, considering the purpose, it is probably to generate a static array dependent on a specific property and let the user edit the properties in the array.

If you change the count of elements in this generated array, it loses consistency with the fact that it was “generated dependent on a specific property”.

For example, what I am doing now is to specify a root bone and an end bone and generate an array with all joints in between as elements, but it must prevent the user from changing the count of elements. Rather, I don't see why only movable is prohibited in static mode.

I think tokage would be ok if we renamed it, but kept the same functionaility.

I sent #101422 as alternative.
