Move libsigchain out of static/shared properties
Using the static/shared properties causes Soong to skip the
optimization that reuses .o files between the static and shared
variants of a library. libart uses static.static_libs and
shared.shared_libs to select between libsigchain and
libsigchain_dummy. This doesn't actually do anything, because
dependencies from the static variant are only used to import
includes. Always use libsigchain in shared_libs, the final
binary that links against static libart will pull in the
correct libsigchain_dummy dependency through
libart_static_base_defaults. This halves the number of times
that the code in art/runtime is compiled.
Also make libsigchain and libsigchain_dummy export their includes
so that libart doesn't need to manually specify include_dirs.
Test: m libart
