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
