This removes all the cache/session/view hooks from the lsp and instead
uses normal introspection from the client to find all the entities
rather than keeping shadow copies of the object graph in the debug page
handler.
This required the addition only of the ability to view the sessions open
on a cache and exposing the unique identifier for all the objects, both
of which are useful and reasonable things to have in the API anyway.

In addition to adding a `go mod vendor` command option, which can be
exposed via an editor client frontend, we show a suggestion to users who
experience the "inconsistent vendoring" error message.
The main change made here is that we save the view initialization error,
and we return it if the view has absolutely no metadata. This seems
reasonable enough, but my fear is that it may lead to us showing
outdated error messages. I will spend some time improving the handling
of initialization errors in follow-up CLs.

I was curious about why were logging errors during type-checking in
tests, and the answer turned out to be a bit more sinister than I
expected. We were getting type error messages without filepaths, so I
tried to reproduce it in the playground and wasn't able to. I realized
that these errors were coming from were coming from the "fixed" version
of the AST that we pass to the type checker.
Adding fake positions to our fake Cond statements trivially fixes the
logging issue, but it does nothing to handle the fact that the error
makes no sense to the user - because it applies to something that's not
in the source code. I figured we have two options: (1) skip type errors
for all packages with "fixed" ASTs, or (2) add something to the error
messages to indicate that the source code may not match. Starting with
(1) here, and if it becomes a problem, we can move to 2. All ASTs that
we fix have *ast.BadExpr in them, meaning that, by definition they have
parse errors which we will preferentially show those errors to users in
diagnostics (so I'm not sure how to test this).

This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.
This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.
A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

inside the switch statement anymore, so we don't know to offer "case"
and "default" candidates. To work around this, we move the closing
brace down one line yielding:
switch {
}
Second I had to add logic to manually extract the completion prefix
inside empty switch statements, and finally some logic to offer (only)
"case" and "default" candidates in empty switch statements.

This change makes ModHandle and ModTidyHandle return a ModData structure that only contains an error if something goes wrong when parsing the .mod files.

When caching file data specific to a session (anything with a Version or
tied to a view), we now need to be more careful about the existence of
multiple sessions.
This change fixes a few places where we appear to cache session data
without explicitly referring to the session. In principal this could
cause data corruption in multi-session gopls instances, but I have not
been able to force this to occur in either manual or automated testing.
Also fix a data race to the unsaved overlays:

Reading the docstring, it looks like the sense of the type assertion was
accidentally inverted in this function. Fix it to what I believe was
intended.

This change attaches a modTidyHandle to the snapshot instance and tries to reuse it as often as possible. It also modifies the modTidyKey to include the files that have not yet been saved. This was necessary because `go mod tidy` only runs using contents on disk.
So, if a user decides to add an import that is not in their modcache, we run diagnostics as normal and the ModTidyKey's imports field gets updated with the new import, we run `go mod tidy` but since the file was not saved yet, nothing changes. Then when the user eventually saves their file, we do not rerun `go mod tidy` because the imports hash has not changed from the time the file was in overlay to the time the file was saved on disk. To be able to account for this, we need the invalidate the ModTidyKey when imports change between saves.

This allows us to register a telemetry exporter that works with mulitple active
debug instances.
It also means we don't have to store the debug information in our other objects.

In all cases, use a Logf field to configure debug logging. Non-nil means
that logging is enabled through the given function.
Fixes accidental debug spam from goimports, which had a separate Debug
flag that was supposed to guard logging, but wasn't used when creating
the gocommand.Invocation.

A small collection of fixes: (1) Don't reload packages with missing
dependencies unless imports change. (2) Show the error message from the
initial workspace load to the user.
Also, a small fix for deletion suggested fixes - upgrading to the latest
version of the VS Code language client revealed that I had made a
mistake there.
