Make hyprctl setcursor better (support XCursor themes, also give fail message)

[ikalco]

Describe your PR, what does it fix/add?

makes it so that hyprctl setcursor can be used to change cursor theme between Hyprcursor and Xcursor

also addresses these issues

• setcursor doesn't apply immediately #4221, by removing this code
  

  Hyprland/src/managers/CursorManager.cpp

  Lines 269 to 270 in de9798f

  	if (std::round(highestScale * m_iSize) == m_sCurrentStyleInfo.size)
  	return;

• hyrctl setcursor should throw error if cursor theme doesn't exist #5232, and adding this too
  

  Hyprland/src/debug/HyprCtl.cpp

  Lines 1066 to 1069 in deb7c4f

  	if (!g_pCursorManager->changeTheme(theme, size))
  	return "failed to set cursor";
  	return "ok";

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

This PR also requires a change in hyprcursor, see hyprwm/hyprcursor#43

The git blame for these lines is for a bug fix, but I believe this was left over when CursorManager was later changed?
either way code should still work the same, just a little less efficient i guess

Hyprland/src/managers/CursorManager.cpp

Lines 269 to 270 in de9798f

	if (std::round(highestScale * m_iSize) == m_sCurrentStyleInfo.size)
	return;

Is it ready for merging, or does it need work?

No, I need to get hyprcursor PR merged first (hyprwm/hyprcursor#43)
tested on my machine

• switching between xcursor and hyprcursor
• and between xcursor and xcursor
• and hyprcursor and hyprcursor
• and different sizes for both

You gotta compile hyprcursor and make Hyprland compile with new header and lib.
I just cmake installed the other PR and then compiled and ran Hyprland
