editor/snippets: expand on snippet commands & keybinds

Browse source 
- Introduces the +snippets/new (SPC s n) command for creating a new
  private snippet
- Introduces the +snippets/new-lias (SPC s N) command for creating a new
  private snippet alias, which will invoke another snippet (you will be
  prompted to select one). This will only work with the emacs-snippets
  library bundled with Doom Emacs, however, as it depends on its API.
- Introduces +snippets/edit (SPC s c) for modifying existing snippets.
  How this differs from yas-visit-snippet-file is it will copy the
  contents of built-in snippets into a buffer primed for your private
  snippets (in DOOMDIR/snippets), while yas-visit-snippet-file will
  simply open the originating snippet.
- Introduces the +snippets/find (SPC s ?),
  +snippets/find-for-current-mode (SPC s /) and
  +snippets/find-private (SPC s f) commands for, respectively, finding a
  snippet file among *all* directories in yas-snippet-dirs, finding a
  snippet for the current major mode (plus parents), and finding a
  snippet from among your private library. This opens built-in snippets
  in read-only mode, but you can press C-c C-e to open it in
  +snippets/edit.
