[IMP] base: add "defer" and "lazy" load options to assets

Thanks to this commit, when using the `t-call-assets` command, we can
use the "defer_load" attribute or the "lazy_load" attribute which will
respectively add the "defer" HTML attribute on the script tags and
replace the "src" attribute of the script tags with a "data-src" one.

In the lazy case, it is up to a custom page script to replace the
"data-src" attribute with the "src" attribute at the appropriate time.
This will be done in a future commit of this PR.
