ccache: Separate out into its own class
Currently, ccache is used if it is present. When building from scratch it gives no performance improvement and creates a ton of empty directories even when its not in use. This change moves ccache support to a bbclass file which the user can choose to enable. This should make builds more determinstic and make it easier/clearer to the end user when its being used and when it is not. (From OE-Core rev: 2acf8da4f13c175ea818b9514677b7059de1e3e2) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
