Allow user to optionally do Unity full recompile on hot reload compilation failure

This should be opt in from the menu (for automatic workflow)

FastScriptReload.Editor.FastScriptReloadManager.TriggerReloadForChangedFiles - is executing compilation and marking down DynamicFileHotReloadState for changed files, it makes sense to add additional full-reload logic in here.

As for only executing when user opted in, PlayerPrefs can be added to FastScriptReload.Editor.FastScriptReloadPreference

as boolean, eg public static readonly ToggleProjectEditorPreferenceDefinition EnableExperimentalThisCallLimitationFix = new ToggleProjectEditorPreferenceDefinition("(Experimental) Enable method calls with 'this' as argument fix", "EnableExperimentalThisCallLimitationFix", true)

then rendering that in options screen can be achieved by adjusting FastScriptReload.Editor.FastScriptReloadWelcomeScreen.CreateLeftSections

and perhaps adding additonal options to 'Reload' screen, like so

new GuiSection("Options", new List<ClickableElement>
{
	new ChangeMainViewButton("Reload", (screen) =>
	{
		const int sectionBreakHeight = 15;
		GUILayout.Label(
			@"Asset watches all script files and automatically hot-reloads on change, you can disable that behaviour and reload on demand.",
			screen.TextStyle
		);

		using (LayoutHelper.LabelWidth(320))
		{
			ProductPreferenceBase.RenderGuiAndPersistInput(FastScriptReloadPreference.EnableAutoReloadForChangedFiles);
		}
		GUILayout.Space(sectionBreakHeight);
		
		//TODO: add at correct place
