apex: install hwasan lib if depended on libc

There're two ways to enable hwasan:
- global setting: TARGET_SANITIZE=hwaddress
- individual setting: sanitize: { hwaddress: true }

This change covers both cases by looking up if com.android.runtime is
hwaddress santized or not.

Bug: 156678661
Test: m (soong test added)
