This change adds support for returning versions along with file URIs, so
that the client can know when to apply changes. The version is not yet
propagated along to the internal/lsp/cache package, so this change will
have no effect (VS Code ignores a version of 0 and still applies the
changes).
A few minor changes made in the rename code (to remove the view
parameter). Some minor staticcheck fixes.

This change does not complete the work to handle snapshots correctly,
but it does implement the behavior of re-building the snapshot on each
file invalidation.
It also moves to the approach of caching the FileHandles on the snapshot,
rather than in the goFile object, which is now not necessary.
Finally, this change shifts the logic of metadata invalidation into the
content invalidation step, so there is less logic to decide if we should
re-load a package or not.

same set of files, but be a test variant. Add the ID to the key to avoid
clobbering entries in the cache.

Now when a file is deleted we force the file's packages to refresh
go/packages metadata, and kick off diagnostics.
I made a couple other changes to watched file handling:
- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.

When a file changes on disk, there are two basic cases. If the editor
has the file open, we want to ignore the change since we need to
respect the file contents in the editor. If the file isn't open in the
editor then we need to re-type check (and re-diagnose) any packages it
belongs to.
We will need special handling of go.mod changes, but start with
just *.go files for now.
