Change span to hide its fields and have validating accessors
This catches the cases where either the offset or the position is being used
when it was not set.
It also normalizes the forms as the API now controls them, and allows us to
simplify some of the logic.
The converters are now allowed to return an error, which lets us cleanly
propagate bad cases.
The lsp was then converted to the new format, and also had some error checking
of its own added on the top.
All this allowed me to find and fix a few issues, most notably a case where the
wrong column mapper was being used during the conversion of definition results.

This change brings back handling for circular imports, which was removed

However, since we are type-checking from source, we still end up having

Additionally, we propagate the errors of type-checking to the
diagnostics so that the user can actually see some of the problems.

This change adds an additional cache for type information, which here is
just a *packages.Package for each package. The metadata cache maintains
the import graph, which allows us to easily determine when a package X
(and therefore any other package that imports X) should be invalidated.
Additionally, rather than performing content changes as they happen, we
queue up content changes and apply them the next time that any type
information is requested.

This removes the last dependency on the cloud.google.com/go module,
