feat(pick): move pickers to extras (telescope still the default) (#3606)

## What is this PR for?

Refactoring of pickers in LazyVim:

- [x] telescope moved to extras
- [x] dressing was moved to the telescope extra. Not needed with fzf-lua
and noice
- [x] when none of the two is enabled, then telescope will be enabled
- [x] when using `:LazyExtras` to enable fzf-lua, the telescope spec
will never be parsed
- [x] when not using `:LazyExras`, the spec will be parsed, but one of
the two will be disabled.
- [x] only one picker extra can be used to prevent issues
- [ ] cleanup lsp keymaps
