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

Certain Intel Meteor Lake specific features are only enabled in
production silicon (not available in early SoC aka pre-production
silicon).
- SPI usage for production SoC is much optimized compared to pre-
production silicon.
- MIPI driver requires a way to identify between pre-prod vs prod
silicon.

This patch adds config options to select the Pre-Production
aka Engineering Silicon (ES). The mainboard users can specify which
underlying SoC is being used for the target platform.

BUG=b:300652989
TEST=No change in the functionality, just added new configs.
