soc/intel/pantherlake: Add configs for pre-production silicon

Browse source 
This patch introduces a new configuration option
`SOC_INTEL_PANTHERLAKE_PRE_PRODUCTION_SILICON` that allows users to
specify if their mainboard is using Panther Lake pre-production silicon
aka Engineering Silicon (ES) with pre-production signed ME Firmwares.
The default value is set to 'n', ensuring it is disabled unless
explicitly chosen.

BUG=b:424355826
TEST=No change in the functionality, just added new configs.
