soc/intel/tigerlake: Hook up FSP hyper-threading setting to option API

Select `HAVE_HYPERTHREADING` and hook up the hyper-threading setting
from the FSP to the option API so that related mainboards don't have to
do that. Unless otherwise configured (e.g. the CMOS setting or overriden
by the mainboard code), the value from the Kconfig setting
`FSP_HYPERTHREADING` is used.

Also, remove related code from the mainboard starlabs/laptop/tgl, since
it is obsolete now.
