This is a straight move of some code with no changes.
It splits the part of the telemetry code that will become a standalone library from the bit that belongs in the lsp.

This change eliminates the need for the package cache map, and instead
stores package type information in the store. We still have to maintain
invalidation logic because the key is not computed correctly.

means that we can easily access both the AST and token via the package,

This change adds supports for a package belonging to multiple files.
It requires additional packages.Loads for all of the packages to which a
file belongs (for example, if a non-test file also belongs to a package's
test variant).
For now, we re-run go/packages.Load for each file we open, regardless of
whether or not we already know about it.
This solves the issue of packages randomly belonging to a test or not.
Follow-up work needs to be done to support multiple packages in
references, rename, and diagnostics.

This change trims the function bodies from the ASTs of files belonging to
dependency packages. In these cases, we do not necessarily need full
file ASTs, so it's not necessary to store the function bodies in memory.
This change will reduce memory usage. However, it will also slow down
the case of a user opening a file in a dependency package, as we will
have to re-typecheck the file to get the full AST. Hopefully, this
increase in latency will not be significant, as we will only need to
re-typecheck a single package (all the dependencies should be cached).

Now the "type" of a *ast.PkgName is the package it points to. Of
course, a package is not a real types.Type, but we can still jump you
there. We have to pick one of the package's files, so we choose the
longest one, hoping it is the most interesting.
Similarly, the "definition" of an *ast.ImportSpec is the package being
imported.
I also added a nil check for the package in SignatureHelp. This panics
for me occasionally.
