devtool: add sdk-install subcommand

Add the ability to install additional pre-built items (from shared
state) into the extensible SDK. This can already be done implicitly by
adding something to DEPENDS within a recipe you're working on and then
running "devtool build", but it's useful to be able to explicitly
install things particularly if you're using the extensible SDK as a
traditional toolchain.

Note that for this command to be useful you need to have SSTATE_MIRRORS
set in your SDK configuration, and that mirror needs to be populated
with sstate artifacts for recipes you wish to be able to install.
