accel/tcg: Add debuginfo support

Browse source 
Add libdw-based functions for loading and querying debuginfo. Load
debuginfo from the system and the linux-user loaders.

This is useful for the upcoming perf support, which can then put
human-readable guest symbols instead of raw guest PCs into perfmap and
jitdump files.
