Switch car-lib over from doclava to metalava
The platform API files are about to switch to signature file format
v2, which doclava cannot parse, so updating this build to using API
check via metalava instead of doclava.
Note: Metalava checks for additional API and docs problems which
doclava did not; some of these are errors which would fail the
build. Therefore, we turn off these warnings until the source
code is fixed.
Test: make docs
