fix(lsp): fix rename capability checks and multi client support (#18441)

Adds filter and id options to filter the client to use for rename.
Similar to the recently added `format` function.

rename will use all matching clients one after another and can handle a
mix of prepareRename/rename support. Also ensures the right
`offset_encoding` is used for the `make_position_params` calls
