Allow locking axes on Follow modifier

[aXu-AP]

This functionality is used for sidescroller (2.5D) and top-down views.

Definitely a good addition. I kinda wish GDScript had a feature like bitfields in C++ to make the masking look cleaner, but maybe it can get revisited in the future.

There's possibility to group variables in inspector, but it doesn't look much better.
Inspector plugin could be a solution to make it cleaner but is it overkill?

Oh, I'm specifically referring to using the variables in code.

//C++
#include <iostream>

struct AxisFlags
{
  // Each of these will take up 1 bit abd be packed into a single byte
  bool x : 1{ false };
  bool y : 1{ false };
  bool z : 1{ false };
};

void main()
{
  AxisFlags enabledAxes{};
  std::cout << sizeof(enabledAxes) << '\n'; // 1
  enabledAxes.x = true;
  if (enabledAxes.y)
  {
    //Much easier to read this way
  }
}

Ah sorry I must have been half asleep. That definitely would be a nice functionality! Currently enums are closest we have (but for use case as simple and unchanging as XYZ I felt hardcoding the bits were better fit).
