Add an SDK_EXT_TYPE value for the extensible SDK which installs the toolchain by default (and possibly even includes the sstate artifacts in the tarball if they aren't too large). This would allow us to have reasonably-sized eSDK installers that can be installed and immediately used as a toolchain from an IDE, for example.
As it happens I added an extra variable to control this rather than an extra SDK_EXT_TYPE value, though it does automatically get set on (to address bug 9257) when SDK_EXT_TYPE is "full".
