Rebecca Stambler 0a5cd10191 internal/lsp: handle unknown revision in go.mod file
This change ensures that, when the initial workspace load fails, we
re-run it if the go.mod file changes. Previously, if a user opened a
workspace with a corrupt go.mod file, we never recovered.

To reinitialize the workspace on-demand, we use the initializeOnce field
as an indicator of whether or not we should reinitialize. Every call to
awaitInitialized (which is called by all functions that need the IWL),
passes through the initialization code. If a retry isn't necessary,
this is a no-op, but if it is, we will call the initialization logic.
Only the first attempt uses a detached context; subsequent attempts can
be canceled by their contexts.

To indicate that we should reinitialize, we call maybeReinitialize.
Right now, we only call this when the go.mod file changes. In the
future, we may need it in other cases.

Fixes golang/go#38232
