OpenTK.Core 4.7.6

BREAKING: Changed the default value of `NativeWindowSettings.Flags` from `ContextFlags.Default` to `ContextFlags.ForwardCompatible` for better out of the box macos support. (@NogginBops) API: Added `NativeWindowSettings.TransparentFramebuffer` and `NativeWindowSettings.VSync`. (@NogginBops) API: Component-wise `Lerp` methods for `float` and `double` vector types. (@g7ChoGXh) API: Implemented `IFormattable` for most `OpenTK.Mathematics` types. (@g7ChoGXh) API: Add bindings for `EXT_fragment_shading_rate`. (@BoyBaykiller) API: Added casts from `Vector2i` and `Vector2` to `System.Drawing.Point`/`System.Drawing.Size` and `System.Drawing.PointF`/`System.Drawing.SizeF` respectively. (@NogginBops) API: Added missing entries in `SizedInternalFormat`. (@BoyBaykiller) API: `BinaryFormat` now contains the `ShaderBinaryFormatSpirV` enum value. (@NogginBops) FIX: Many fixes related to `NativeWindow.WindowState`. Most notably, going from fullscreen to maximized and back works correctly. (@NogginBops) FIX: `MonitorInfo.WorkArea` now gives the correct values. (@utkumaden) FIX: Spelling and formatting corrections in documentation. (@sg-wizard-maker) FIX: Math types now change their formatting when `CurrentCulture` is changed. (@g7ChoGXh) FIX: `Matrix4x3`/`Matrix4x3d` now print their final row. (@NogginBops) FIX: On Windows, setting `GameWindowSettings.UpdateFrequency` and `GameWindowSettings.RenderFrequency` should be more accurate. For details see documentation for `GameWindow.Run()`. (@NogginBops) The OpenTK solution should now build directly in Visual Studio with no need to run `build.cmd` any more. (@NogginBops)
