Subject: [PATCH] [FIX] web: preload font awesome font for frontend layouts

This commit adds an easy improvement fixing a page speed warning: the
font awesome font (declared in a font-face in assets_common) can be
preloaded.

The only problematic point was that font-awesome defines the font by
a series of URL using different font formats. Only one can be
preloaded (otherwise you would load files for no reason). As all Odoo
supported browsers use the woff2 format, we only preload that one. At
the cost of a warning for other browsers which use a different format.
