compatibility matrices: move to soong
* Kernel config requirements are built as
separate rules in kernel/configs. All kernel requirements
(including minlts and configs) are represented there.
* device framework compatibility matrix and final
framework compatibility matrix need special environment
variables, so they are not generic enough to be written
in the soong rule.
See compatibility_matrices/Android.bp for sample usages.
Test: builds and compare output before change
