[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. task-2350647 closes odoo/odoo#60715 X-original-commit: 60c787679260a97c58f399af1a51d7549429f979 Signed-off-by: Quentin Smetz (qsm) <qsm@odoo.com>
