internal/lsp: support running `go mod tidy` as a code action
This changes adds basic support for running `go mod tidy` as a code
action when a user opens a go.mod file. When we have a command
available like `go mod tidy -check`, we will be able to return edits as
part of the codeAction. For now, we execute the command directly.
This change also required a few modifications to our handling of file
kinds so that we could distinguish between a Go file and a go.mod file.
