platform/x86: alienware-wmi: Split DMI table

Split thermal features into a new DMI table to support upcoming file
split. While at it:

Rename quirk_entry -> alienfx_quirks,
Rename quirks -> alienfx

and change hdmi_mux, amplifier and deepslp types to bool, because they are
already being implicitly used as bools.
