Previously, our file watching only considered the root directory of the
view, which may not include the entire module or its replaced
dependencies. Now we expand our watching to include the whole module.
As part of testing this, I noticed that VS Code's file watcher actually
only sends updates for files in the workspace, even if we request
notifications for all files in the module. I filed an issue to ask about
this: https://github.com/microsoft/vscode-languageserver-node/issues/641.

This CL got away from me a little.
For a number of reasons, the existing goimports API of passing in values
for various GO* values was not working. For one, the number of necessary
variables kept growing. For another, we tried to avoid calling `go env`
in GOPATH mode by using `build.Default`, but that turns out to be buggy;
see golang/go#39838. And finally, it created massive confusion about
whether the values were intended to be read from the OS environment, or
fully evaluated by the `go` command.
There are only two users of the internal imports API, so there really
shouldn't need to be more than two modes. For the command line tool, we
have to call `go env` to deal with the `go/build` bug. So we just do it.
Tests use that same path, but can augment the enviroment to set
themselves up. In contrast, `gopls` needs to fully specify the
environment. It can simply pass in the fully evaluated GO* values.
Finally, make the change I was actually here to make: propagate
GOMODCACHE and use it where appropriate.

This change separates out different functions of mod handles.
Previously, we had ModHandle and ModTidyHandle. ModHandle was used to
parse go.mod files and get the results of `go mod why` and possible
dependency upgrades.
Now, we factor this out into 4 handles: ParseModHandle, ModWhyHandle,
ModUpgradeHandle, and ModTidyHandle. This allows each handle to be
specific to its own functionality. It also simplifies the code a bit,
as the handles can be written in terms of ParseModHandles instead of
FileHandles.
I may have some follow-up CLs to refactor the `go mod tidy` logic out of
the cache package, though I'm no longer certain that that's a good
choice.

The gopls workspace environment defaults to the process environment in
which gopls was started. This means that when switching environments,
gopls can potentially get a different environment when connecting as an
editor sidecar from when forwarding requests to the daemon.
To (hopefully mostly) mitigate this pain point, inject the Go
environment when forwarding the 'initialize' request, which contains
InitializationOptions containing the 'env' configuration. We could go
further and send the entire os.Environ(), but that seems problematic
both in its unbounded nature, and because in many cases the user may not
actually want to send their process env over the wire. Gopls behavior
should *mostly* be parameterized by gopls binary and Go env, and after
this change these should match for forwarder and daemon.
For go1.15, Explicitly set the GOMODCACHE environment variable in the
regtest sandbox. Without this, regtests were failing in the forwarded
environment because they implicitly shared a module cache.

The cache does not know the sessions associated with it, so the
debug template cannot display them.

Ignore ignored the builtin package and files that start with _. The
latter should already be ignored by "go list". The former seems
like too much effort to me. People shouldn't edit random parts of the
stdlib, and ignoring changes to (e.g.) the Error interface seems like
the least of the trouble they can get themselves into.
Remove it for now. If we get complains I'll re-add it, probably by
rejecting the write entirely somewhere.
We incidentally relied on this in the identifier functions; change those
to treat the builtin package slightly more specially.
