classes/recipes: Switch to use inherit_defer

Now that bitbake supports the use of inherit_defer, switch all conditional
(variable based) inherits to use this instead. This leads to more a more
deterministic user experience since there is no longer an immediate expansion
and later changes to the variables in question (e.g. a bbappend) are
accounted for.

This patch tries to ensure the behaviour before/after remains as unchanged
as it reasonably can, e.g. by always inherting populate_sdk_base. native
and nativesdk continue to need to be inherited last, hence being used
with inherit_defer in a handful of very specific cases.
