River Riddle ff81a2c95d [mlir-lsp-server] Add support for textDocument/documentSymbols
This allows for building an outline of the symbols and symbol tables within the IR. This allows for easy navigations to functions/modules and other symbol/symbol table operations within the IR.

River Riddle f9ea3ebef2 [mlir-lsp-server] Add support for recording text document versions
The version is used by LSP clients to ignore stale diagnostics, and can be used in a followup to help verify incremental changes.

River Riddle b3911cdfc8 [mlir-lsp-server] Add support for sending diagnostics to the client
This allows for diagnostics emitted during parsing/verification to be surfaced to the user by the language client, as opposed to just being emitted to the logs like they are now.

River Riddle 751c14fc42 [mlir][mlir-lsp] Add a new C++ LSP server for MLIR named mlir-lsp-server
This commits adds a basic LSP server for MLIR that supports resolving references and definitions. Several components of the setup are simplified to keep the size of this commit down, and will be built out in later commits. A followup commit will add a vscode language client that communicates with this server, paving the way for better IDE experience when interfacing with MLIR files.

The structure of this tool is similar to mlir-opt and mlir-translate, i.e. the implementation is structured as a library that users can call into to implement entry points that contain the dialects/passes that they are interested in.

Note: This commit contains several files, namely those in `mlir-lsp-server/lsp`, that have been copied from the LSP code in clangd and adapted for use in MLIR. This copying was decided as the best initial path forward (discussed offline by several stake holders in MLIR and clangd) given the different needs of our MLIR server, and the one for clangd. If a strong desire/need for unification arises in the future, the existence of these files in mlir-lsp-server can be reconsidered.
