fix(lsp): update TypeScript imports when files move (#1346)

vtsls has no workspace/willRenameFiles: after didRenameFiles it updates
imports itself, behind a prompt sent as window/showMessageRequest. The
IDE shows that request as a message without choices, so moving a
TypeScript or JavaScript file never updated the imports of the files
that use it.

For a tsserver-backed server without willRename filters, the IDE now
asks tsserver for the edits up front (getEditsForFileRename through
typescript.tsserverRequest). The edits join the move's preview and undo
like any server's. The server's own update is turned off
(updateImportsOnFileMove.enabled = "never"), so it no longer prompts.
