build-configs: x86-chromebook: enable TPM

This adds the required configs to enable the cr50 i2c and spi TPM chips present on Chromebook devices. The drivers expose /dev/tpm devices which will then be used by tpm2-tools in Debian images or a custom TPM userspace stack in ChromeOS images exercisable via the TAST test suite.
