mb/google/rex: Refactor CSE config options for model-specific settings

This patch refactors CSE config options, moving the selection of:

* `SOC_INTEL_CSE_LITE_SKU`
* `SOC_INTEL_CSE_PRE_CPU_RESET_TELEMETRY_V2`
* `SOC_INTEL_CSE_SEND_EOP_ASYNC`

from the generic `BOARD_GOOGLE_REX_COMMON` to individual board models.
This enables finer-grained control over CSE features and sync behavior
on different Rex and variants platforms.

Specifically:

* `google/rex0`: Selects `SOC_INTEL_CSE_LITE_SKU` for CSE sync within
                 coreboot.
* `google/rex64`: Selects `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` and
                  `SOC_INTEL_CSE_SEND_EOP_BY_PAYLOAD` to defer CSE sync
                  to the payload.
