Refactor linker/Android.bp for native-bridge
Define a "linker_bin_template" cc_defaults module that a native bridge
implementation can inherit to define a guest linker.
Break the debuggerd_init call off into separate
linker_debuggerd_{android,stub}.cpp files to allow opting in/out of the
debuggerd integration without needing to change how linker_main.cpp is
compiled. (This is necessary for a later commit that moves
linker_main.cpp into a new static library.)
Test: bionic unit tests
Bug: none
