Rebecca Stambler 3c1b287bbd internal/lsp: await the initial workspace load in ModHandle
ModHandle races with the initial workspace load if the go.mod file does
not yet exist. We should await for the initial workspace load to
complete before proceeding with update codelenses, etc.

Part of trying to figure out the flakes in golang/go#39504.
Also a few staticcheck fixes, and fix the Windows line endings in
fill_struct.go, because `git gofmt` complains.
