Eglot: Add "static-ls" to Haskell LSP listHEADmaster

This is an alternative language server for Haskell.  Intended to be
faster and not use as much memory as haskell-language-server.
Making it a backup with lower precedence if both exist.
* lisp/progmodes/eglot.el (eglot-server-programs): Add "static-ls".
