crypto: spacc - Add SPAcc Kconfig and Makefile

This commit introduces the Kconfig and Makefile for the new dwc_spacc
Security Protocol Accelerator driver. It wires up the build system entries
and configuration options for various SPAcc features.

[Severity: Medium]
Is a select for CRYPTO_SHA3 missing here?

The SPAcc driver implements hardware acceleration for SHA-3 algorithms and
requires the software SHA-3 algorithms as fallbacks. If CONFIG_CRYPTO_SHA3
is not enabled, the driver's probe sequence will fail to find the fallback
and silently skip registering the SHA-3 hardware acceleration algorithms.
