arch/arm64: Add Kconfig option ARM64_BL31_OPTEE_WITH_SMC

Add a new Kconfig option ARM64_BL31_OPTEE_WITH_SMC to control whether to
build the OP-TEE dispatcher for BL31. This config also enables the BL31
build option OPTEE_ALLOW_SMC_LOAD, which allows loading the OP-TEE image
after boot via a Secure Monitor Call (SMC). For ChromeOS devices,
CROS_WIDEVINE_SMC is also enabled to allow passing secrets from firmware
to OP-TEE.
