We pass around verb/args/wd in many places. Bundle them up as an
Invocation instead. goCommandInvocation now updates and returns an input
Invocation.
packages.Config is conceptually an extra layer of parsing and
type-checking on top of a go list invocation. It doesn't make sense for
us to construct the latter using the former. A later CL will construct
the Config in terms of the Invocation; for now duplicate a bit of logic.
Use the environment in the cache key for various module operations
rather than the Config hash. I'm not sure either is fully correct but I
think the environment captures everything that's likely to matter. This
way we don't need Configs in those functions at all.

This CL switches from automatically registering the semantic tokens
capability to dynamic registration. This allows us to turn it on and
off as the option is switched--otherwise it defaults on always.
To achieve this, we also have to set session options on
didChangeConfiguration. It turns out that the passed-in "changed"
parameter can be null, which is why we always refetch the workspace

(packageID, parsed files, and deps). Furthermore, when using a gopls
daemon this causes unnecessary cache misses, because the packages.Config
includes things like working directory that no longer matter once other
inputs to type checking have been computed.
Add an experiment flag that removes the packages.Config from the cache
key. An experiment is used to stage this change as comprehensively

FileHandles with stat errors didn't have their URIs populated. It's
probably reasonable to expect URI and Kind to work on them.

We should be able to smoothly add and remove modules from the workspace.
This change moves the module-related fields from the view into the
snapshot so that they can be easily modified and recomputed. The
workspace module is now a workspaceModuleHandle.

1.16 wants to set GO111MODULE=on. There are, AFAIK, two differences
between "auto" and "on". First, if you're in a directory outside of GOPATH
and with no go.mod, "on" will run in module mode with GOMOD=os.DevNull.
I don't think we care very much about that. Second, if you're in GOPATH
with no go.mod, "on" will run in module mode, breaking GOPATH mode.
Breaking GOPATH mode may be desirable for the go command generally, but
for gopls I think it will lead to an unnecessarily bad user experience.
Users will find out when they do their first build or test; there's IMO
no need to also break their editor.
Flip the default back to "auto".

We were previously behaving as though the slice/map values in the
options struct could be modified directly. The options should be cloned
before modification. Also, convert any usage of source.Options to
*source.Options.
