cc bp2build for sysprop_library modules

This CL implements bp2build functionality for the cc outputs of
sysprop_library modules. cc_* modules depending on sysprop sources
will be handled in a later CL.

Bug: 244439349
Test: b build //system/libsysprop/srcs/...
Test: Inspect BUILD.bazel
Test: Unit tests
