Exported includes have been maintained along with other C/C++ flags. This makes dependencies unclear, and users have had to parse flags to get exported directories. This separates exported includes and exported flags, thus making data more structured and explicit. Bug: 132818174 Test: m Change-Id: I5c25ac2224988c4a67e4db6fd6e4d39090b74041
