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 change adds severity levels to source.Diagnostics, allowing us to
pass this information along to the LSP. This allows compiler errors to
show up in red, while vet results show up in green.

This starts hooking up the analysis framework into the LSP. It runs
the Tests analysis (which I think might be the only one that doesn't
need facts or results) and reports its diagnostics if there are
no parse or typecheck failures.
Next step: figure out how to pass through results.

This change makes sure to handle escaped characters, for instance, files
in the module cache contain "@" in the path. Also, return errors when a
package is not found for a file.

Refactor code as a follow-up to
https://go-review.googlesource.com/c/tools/+/154742.
Also, change every instance of "source.URI()" to "fromProtocolURI", so
that we can add a better implementation of that later on (for Windows
support).

Added a View interface to the source package, which allows for reading
of other files (in the same package or in other packages). We were
already reading files in jump to definition (to handle the lack of
column information in export data), but now we can also read files in
diagnostics, which allows us to determine the end of an identifier so
that we can report ranges in diagnostic messages.

This change separates a cache package out of the
golang.org/x/tools/internal/lsp/source package. The source package now
uses an interface instead a File struct, which will allow it be reused
more easily. The cache package contains the View and File structs now.

I realized this was a mistake, we should try to keep the source
directory independent of the LSP protocol itself, and adapt in
the outer layer.
This will keep us honest about capabilities, let us add the
caching and conversion layers easily, and also allow for a future
where we expose the source directory as a supported API for other
tools.
The outer lsp package then becomes the adapter from the core
features to the specifics of the LSP protocol.

This allows us to write the lsp verbs in terms of a stable underlying source
management layer.
This should make it easier to refactor the underlying layer to add more powerful
caching and incremental modes as we go.

Any time a file is changed, we compute diagnostics for its package and
return them to the client. No caching is implemented yet, so we parse
and type-check the package each time.
