Fix language server renaming when parent directory does not exist (#43499)

Update the `fs::RenameOptions` used by
`project::lsp_store::LocalLspStore.deserialize_workspace_edit` in order
to always set `create_parents` to `true`. Doing this ensures that we'll
always create the folders for the new file path provided by the language
server instead of failing to handle the request in case the parent

- Introduce `create_parents` field to `fs::RenameOptions`
- Update `fs::RealFs.rename` to ensure that the `create_parents` option
is respected

Closes #41820 

Release Notes:

- Fixed a bug where using language server's file renaming actions could
fail if the parent directory of the new file did not exist
