Minimize the issues at master by not running workspace-level diagnostics
on mod file changes. Once the initial workspace load stabilizes we will
be able to go back to that approach.
Also, a couple of minor changes along the way while debugging.

We don't distinguish between genuine errors and context cancellation in
diagnostics, which often results in superfluous logging of these errors.
Avoid spamming the logs with them by checking.
Also, remove the logic for sending undelivered diagnostics. It's a relic
of old bugs and isn't useful.

The early return logic for didOpen events in
(*snapshot).invalidateContent was preventing the creation of a new
snapshot, which was in turn stopping the versions from being updated.
This exposed a fundamental issue in the way we were calculating
workspace diagnostics. Since we weren't waiting for diagnostics to be
completed for an entire snapshot before replying that the server had
been initialized, snapshots were being cloned without any type
information. For quickfix code actions, we assume that we have all
information cached (since we need to have sent the diagnostics that the
quickfix is mapped to), so we were not finding the cached analysis
results.
To handle this in the short-term, we key analyses by their names, and
then regenerate results as-needed for code actions. This is technically
more correct than simply assuming that we have the analyses cached. In a
follow-up CL, I will send a follow-up that will make sure that
snapshots "wait" on each other to be fully constructed before being
cloned.

This change runs diagnostics on all packages in the workspace, instead
of just open files. We also want to avoid invalidating the type
information for a newly-opened file (since we should have it be default
now), so handle that case.
This causes a large increase in memory usage in the
internal/lsp/cmd tests, so to handle that, share an app between all of
the tests, rather than creating one per-test type.

This change stops the memory leak from happening. It does not stop the
large number of allocations done by analysis, however, so these still
need to be prevented through correct cancellation.

This change moves to the approach of caching the analysis using the
memoize package. This means that we will do less work, as we no longer
need to recompute results that are unchanged. The cache key for an
analysis is simply the key of the CheckPackageHandle, along with the
name of the analyzer.
