soc/intel/alderlake: Disable Intel TXT based on `INTEL_TXT` config

This patch makes the call into TXT lib in order to disable the TXT
if SoC user haven't selected the `INTEL_TXT` config. Disabling TXT
would be helpful to access VGA framebuffer prior calling into FSP-M.

TEST=Able to perform disable_txt and unlock memory which helped to
access VGA framebuffer prior calling into FSP-M.
