This adds a property instead of the global to key off if the debuginfod
resolver should be used to bundle symbols into the capture at the
augmentation point post-capture.
This defaults to off because we do not want to auto-include them when
recording from the GTK UI (as we'd spend a bunch of time not showing a
window) but we do want to include them from sysprof-cli as that could
be running on a remote machine/container/vm with different debug URLs.
In the future, that could be improved with a different UI flow though.

This brings together the two libraries back into one now that the whole
design is pretty well sorted out. They depend on roughly the same libraries
anyway and it's way easier of the single library can both read and write
the capture files (along with bringing in libsysprof-capture symbols in
a single place).
