[IMP] theme_*: adapt New Page template designs for themes

This commit customizes all New Page template designs for every single
theme.

The changes are organized as follow:

When the used blocks are not the default ones:
- the new sequence of block is listed in the `new_page_templates`
manifest entry.
- the blocks are updated in the `new_page_template_sections_..._...`
XML templates accordingly.

After the potential block sequence updates, the `new_page_template.xml`
then first contains the general customization of blocks (those that
apply across all new page templates) then the customization for each
category of page.

Customizations for a specific page are directly below category-wide
customizations of the given block when both exist.
