binconfig-disabled: Add class and use

This adds a binconfig-disabled class which can be used by recipes where
a -config file is installed but we wish to disable it and just rely on
the .pc files instead.

Rather than simply deleting it, we make the script "exit 1" so that it
can be found in PATH and raise a build error rather than something
silently falling back to the build system for example.

Rather than randomly finding -config files, this adds in the
specification of a list of binconfig scripts which is more deterministic
and maintainable moving forward.

This patch converts various users in OE-Core to use this, a world build
of OE-Core tests out ok with this change. There will likely be issues in
other layers however, hence this being a RFT.

kernel-module-split: Add support for KERNEL_MODULE_AUTOLOAD and KERNEL_MODULE_PROBECONF

The current module_autoload_* and module_conf_* variables are error
both ugly and error prone. They aren't registered in the task checksums
so changes to them aren't reflected in the build. This turns out to
be near impossible to fix with the current variable format in any
sensible way :(.

This patch replace module_autoload with the list of variables in
KERNEL_MODULE_AUTOLOAD which is a much simpler and usable API. An
error is printed if an old style variable is encountered. It should
be simple to convert to this.

module_conf_* are harder to deal with since there is data associated
with it, it isn't simply a flag. We need a list of variables that are set
in order to be able to correctly handle the task checksum so we add
KERNEL_MODULE_PROBECONF for this purpose and error if the user hasn't
added a module to it when they should have.
