app_list: do not layout suggested apps and indicators in folder view

changes:
app_list_folder_view ctor/dtor sets/resets |folder_delegate_| in
apps_grid_view. We could use it to determine whether to layout suggested

app_list: update opacity per suggestions container

changes:
Regression comes from https://chromium-review.googlesource.com/c/585398
where each SearchResultTileItemView is paint to layer, so that its
opacity can be controlled. In folder view, we don't layout suggestions
container view. Thus, it is better to make suggestions container view
paint to layer.

Test: test that bug is fixed
