internal/lsp/source: add sortslice analyzer

Browse Source 
The sortslice analyzer warns the user when they're
using a non-slice parameter to sort.Slice. It can
also suggest fixes for 3 different cases of misuse:
  1. The parameter is a pointer to a slice.
  2. The parameter is an array
  3. The parameter is a function with no arguments
    that returns a slice.
