dev/core#1905 rework #17942 with simpler ts strings

[agh1]

Overview

This reworks the template markup for the buttons added in #17942 to get all the markup out of the string to translate with {ts}.

I also set the title for the whole buttons, not just the icons.

Before

Translator has to translate something like

<a class="button " target="_blank" href=%1><i aria-hidden="true" title="Configure Contribution Page" class="crm-i fa-wrench"></i> Configure</a>

You have to hover over the wrench to see "Configure Contribution Page".

After

Translator has to translate "Configure Contribution Page" and "Configure".

You see "Configure Contribution Page" when hovering anywhere over the button.

Technical Details

I used the {crmButton} and {icon} Smarty helpers to cut down on a lot of boilerplate.
