Adapt digest header files to support both original libs and MbedTLS by switching on/off MBEDTLS_LIB_CRYPTO. Introduce <alg>_LEGACY kconfig for legacy hash implementations. sha256.o should depend on SHA256 kconfig only but not SUPPORT_EMMC_RPMB, SHA256 should be selected when SUPPORT_EMMC_RPMB is enabled instead. `IS_ENABLED` or `CONFIG_IS_ENABLED` is not applicable here, since including <linux/kconfig.h> causes undefined reference on schedule() with sandbox build, as <linux/kconfig.h> includes <generated/autoconf.h> which enables `CONFIG_HW_WATCHDOG` and `CONFIG_WATCHDOG` but no schedule() are defined in sandbox build, Thus we use `#if defined(CONFIG_MBEDTLS_LIB_CRYPTO)` instead.
