The .debug_names search is what returns results to `TypeQuery::ContextMatches`,
but we should have functions that can do the same matching. The difference here
in .debug_names is we are trying to live off only the contents of .debug_names
without using and DIEs. `TypeQuery::ContextMatches` uses DIEs. So we might be
able to unify some of the context matching once the context has been extracted
from the .debug_names or from the DWARF, but that is about as far as we should
go.
