This commit adds inlay hint support to the Verilog LSP server. It currently supports two ways of displaying inlay hints: 1. Built-in inlay hints for function calls and module instantiations, showing port types and directions (in/out/inout). 2. User-provided inlay hints through a custom LSP extension method "verilog/putUserProvidedInlayHints", allowing clients to add contextual information to Verilog symbols. The implementation includes: - Protocol extensions for user-provided inlay hints - Visitor pattern for traversing the AST to find hint locations - Support for refreshing hints when they are updated
