b005cdb7 - [ty] Implemented support for "rename" language server feature (#19551)

[ty] Implemented support for "rename" language server feature (#19551) This PR adds support for the "rename" language server feature. It builds upon existing functionality used for "go to references". The "rename" feature involves two language server requests. The first is a "prepare rename" request that determines whether renaming should be possible for the identifier at the current offset. The second is a "rename" request that returns a list of file ranges where the rename should be applied. Care must be taken when attempting to rename symbols that span files, especially if the symbols are defined in files that are not part of the project. We don't want to modify code in the user's Python environment or in the vendored stub files. I found a few bugs in the "go to references" feature when implementing "rename", and those bug fixes are included in this PR. --------- Co-authored-by: UnboundVariable <unbound@gmail.com>
