`firefox`: Simplify config

[Sam Lehman]

Make Firefox config less complex & reduce number of files config is spread across.

Goals

• Minimal updating of extension package hashes/versions.
• home-manager config works as standalone (on non-NixOS systems)
• home-manager inherits/overrides system config.
• Profiles: base (to be extended by all other profiles)
• Profiles: gnome, kde that use DE-specific settings & styles.
• Profiles: default (to match profile of current desktop)
• Profiles: hardened (default + hardening settings that might be inconvenient to use in default profile)
• Profiles: tor-browser (match Tor browser settings)

Profile Features

Default Profile
