Build DEVICE_FRAMEWORK_COMPATIBILITY_MATRIX_FILE

... along with compatibility_matrix.device.xml.
The new module cm.device.xml contains the original content
of empty.xml (kernel configs, sepolicy, etc.) as well
as HALs from DEVICE_FRAMEWORK_COMPATIBILITY_MATRIX_FILE.
This variable points to a framework compatibility matrix
that contains framework HALs as a vendor extension; all
HALs in this file must be optional.

Bug: 65028233
Test: m framework_compatibility_matrix.xml -j and manual inspection
Test: vts_treble_vintf_test
