thermal: fix x86_pkg_temp_thermal.c build and Kconfig

Fix build error in x86_pkg_temp_thermal.c.  It requires that
X86_MCE & X86_THERMAL_VECTOR be enabled, so depend on the latter symbol,
since it depends on X86_MCE (indirectly).

Also, X86_PKG_TEMP_THERMAL is already inside an "if THERMAL" block,
so remove that duplicated dependency.
