Add new customization option `use-package-always-demand`

This is equivalent to adding `:demand t` to all `use-package` declarations,
and has the same semantics as doing so (meaning it can be overridden locally
using `:defer t` in a declaration).

Fixes https://github.com/jwiegley/use-package/issues/423
