lib: Adapt digest header files to MbedTLS
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.
