[cogl] Ensure well defined semantics for COGL_INVALID_HANDLE material layers
Fixes and adds a unit test for creating and drawing using materials with COGL_INVALID_HANDLE texture layers. This may be valid if for example the user has set a texture combine string that only references a constant color. _cogl_material_flush_layers_gl_state will bind the fallback texture for any COGL_INVALID_HANDLE layer, later though we could explicitly check when the current blend mode does't actually reference a texture source in which case binding the fallback texture is redundant. This tests drawing using cogl_rectangle, cogl_polygon and cogl_vertex_buffer_draw.
