GP: Select color in Brush or in Properties

After some artist feedback the material selection was not clear.

Now, the material can be selected in the top bar or in the properties panel.

1) If the material is selected in properties panel, all Brushes except pinned will be assigned to this material.

2) If the material is selected in the brush, the properties panel is updated to set the active material.

Added a new Pin icon to keep locked the material to one brush
