Colin Cross 8fb525db71 Add soong_cc_prebuilt.mk
Add soong_cc_prebuilt.mk for Soong modules to use so they can avoid
going through all of prebuilt_internal.mk, dynamic_binary.mk and
binary.mk.  Also moves stripping support into Soong.

Relands I8b37dda2b449b6b5d48d5b983f43de452f494a1e with fixes for
builds with GENERATE_BREAKPAD_SYMBOLS=true

Bug: 113936524
