Add optional support for switch-buffer previews

Browse source 
When `+ivy-buffer-preview` is non-nil, our various switch-buffer
functions will preview the current candidate buffer, like how
`counsel-switch-buffer` works.

When `ivy-use-virtual-buffers` is non-nil, virtual buffers are *not*
previewed unless `+ivy-buffer-preview` is `'everything`.
