meta-extsdk-toolchain: add meta-recipe to install toolchain into eSDK

Add a meta-recipe to bring the toolchain into the extensible SDK. This
was modelled on meta-ide-support but some adjustments were needed to the
dependency validation function in sstate.bbclass to ensure that all of
the toolchain gets installed into the sysroot. With this, after
installing a minimal eSDK you only need to run the following after
sourcing the environment setup script to get the toolchain:

  devtool sdk-install meta-extsdk-toolchain
