Add header-abi-checker for Vndk abi checks.

header-abi-dumper: dumps abi exported by source files for Vndk.
header-abi-linker: links abi dumps produced by header-abi-dumper.
header-abi-diff: compares linked dumps.

Test: mm -j64 showcommands > make_log in bionic/libc.
      This produced linked dumps in out/soong/.intermediates.
      Copied these dumps to
      prebuilts/abi-dumps/ndk/current/arm64/source-based/.
      Changed the abi and re-ran mm -j64 showcommands > make_log
      confirmed that the build reported compatibility breakge without
      actually failing (advisory mode).
