This change marks any unresolved packages discovered as imports by
go/packages.Load. It re-runs go/packages.Load for any package with
missing imports, which will result in the LSP registering changes in
dependencies.
However, this means that we re-run go/packages.Load on
package's with unresolved imports much more than we normally would, so
it may result in a slowdown or unexpected behavior. I'm not sure if this
is necessarily the correct approach here.

This change trims the function bodies from the ASTs of files belonging to
dependency packages. In these cases, we do not necessarily need full
file ASTs, so it's not necessary to store the function bodies in memory.
This change will reduce memory usage. However, it will also slow down
the case of a user opening a file in a dependency package, as we will
have to re-typecheck the file to get the full AST. Hopefully, this
increase in latency will not be significant, as we will only need to
re-typecheck a single package (all the dependencies should be cached).

The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.
Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".
