Create a Valo icon font for icons used in Valo (#18472)

Valo uses only a handful of icons from Font Awesome. This change
introduces a separate icon font for valo (9KB instead of 80KB) and
decouples Valo from Font Awesome to enable updating Font Awesome
without taking Valo into account.

This change also makes it easy to not load Font Awesome when using Valo
by setting $v-font-awesome:false

For backwards compatibility, Font Awesome is loaded by default
