crypto: testmgr - extend acomp tests for NULL destination buffer

Acomp API supports NULL destination buffer for compression
and decompression requests. In such cases allocation is
performed by API.

Add test cases for crypto_acomp_compress() and crypto_acomp_decompress()
with dst buffer allocated by API.

Tests will only run if CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.
