Chris Parsons 1f6d90f4c7 Create 'cc_prebuilt_test_library_shared' module type 
This new module type allows cc_test modules to depend on prebuilt
shared libraries and have them included as data dependencies alongside
the test binary.

Test: Manually verified to facilitate mk-to-bp migration of
bionic-unit-test prebuilt dependencies (aosp/1339035)
