Problem: luals returns stricter diagnostics with bundled luarc.json
Solution: Improve some function and type annotations:

* use recognized uv.* types 
* disable diagnostic for global `vim` in shared.lua
* docs: don't start comment lines with taglink (otherwise LuaLS will interpret it as a type)
* add type alias for lpeg pattern
* fix return annotation for `vim.secure.trust`
* rename local Range object in vim.version (shadows `Range` in vim.treesitter)
* fix some "missing fields" warnings
* add missing required fields for test functions in eval.lua
* rename lsp meta files for consistency

Problem:
- Notifications are missing from `lsp.Methods`.
- Need a way to represent `$/` prefixed methods.

Solution:
- Generate notifications.
- Use "dollar_" prefix for `$/` methods.
