LSP: initial LSP implementation for IR files to assist with decompilation (#1647)

* lsp: json-rpc example is working, a decent place to start...

* lsp: vendor library

* lsp: cleanup and time to get started

* lsp: commit what i got so far

* lsp: example `initialize` payload

* lsp: switch to `stdio`

* stash

* modularize the lsp implementation

* lsp: implement first actual LSP feature - function names in outline

* lsp: produce document diagnostics

* lsp: remove unused third-party lib

* lsp: support hovering MIPS instructions in IR files

* lsp: basic go-to all-types definition

* stash

* lsp: cleanup code, just need to add it to the release artifacts

* fix some project configuration

* fix linux build

* lsp: add lsp to PR artifacts and release assets

* lsp: address feedback
