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.

Add an autocompletion implementation to the LSP. Also, add a function
that type-checks a package at a certain position, returning an *ast.File
and token.Pos for querying completion.

A file is strongly associated with a view, and knows how to manage it's own
contents.
We can also now track files that are not "active"

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.
