To optimise performance of lsp mode in emacs 27 and above I have introduced a new dotfile variable to define the size of data read from external processes. The default I have set to the recommended setting from lsp-mode. In addition I have introduced a new layer variable for auto-complete-layer to define the minimum prefix length. I have also added instructions to auto-complete's readme how to set these variables to the recommended settings for lsp-mode. Changes inspired from #13507
