Fix copy items' icon not shown in Chrome context menu.

Recently all copy related items' change from png to vector drawable,
this makes TintedDrawable.constructTintedDrawable fail to render the
icon because VectorDrawable does not extend TintedDrawable. Also since
ApiCompatibilityUtils.getDrawable cannot render vector drawable on pre-L
devices, change to use AppCompatResources.getDrawable to render icon for
context menu.
