Implement the ITypeDiscoveryService service

[LeafShi1]

Fixes #9870

Proposed changes

• Add ITypeDiscoveryService in default service container ServiceContainer of IDesignerHost
• Implement the ITypeDiscoveryService service

Root cause of this issue:

• In the PopulateColumnTypesCombo function, the code attempts to obtain an ITypeDiscoveryService instance through the GetService method of IDesignerHost in order to discover all subtypes of DataGridViewColumn.
  However, because ITypeDiscoveryService is not added in the default service container ServiceContainer of IDesignerHost, GetService returns null.

winforms/src/System.Windows.Forms.Design/src/System/Windows/Forms/Design/DataGridViewAddColumnDialog.cs

Lines 657 to 673 in 1d604b5

	private void PopulateColumnTypesCombo()
	{
	_columnTypesCombo.Items.Clear();
	if (!_liveDataGridView.Site.TryGetService(out IDesignerHost? host))
	{
	return;
	}
	ITypeDiscoveryService? discoveryService = host.GetService<ITypeDiscoveryService>();
	if (discoveryService is null)
	{
	return;
	}
	ICollection columnTypes = DesignerUtils.FilterGenericTypes(discoveryService.GetTypes(typeof(DataGridViewColumn), excludeGlobalTypes: false));

Customer Impact

• The DataGridViewColumn can be added normally in DemoConsole project

Risk

• Minimal
