Add PRODUCT_PACKAGES_DEBUG_ASAN

This is a list of modules which should be installed by default, but only on
builds which are set up for Address Sanitizer (via SANITIZE_TARGET=address).

Additionally, add sanitizer-status to PRODUCT_PACKAGES_DEBUG so that all
userdebug builds will have the binary.  Currently, the module has the
"debug" tag but it may go away in the future.
